Hey, I'm an idiot, I took a while to realize the helpful gentleman on the forum is actually the developer of the program! Good work, man, it's a wonderfully useful program, and great fun at the same time!

Happy ending! Everything's fine again, now! But some of the things that happened during the process might interest you perhaps??? So I will relate them, chronologically....

The symptom COMPLETELY changed for no apparent reason. Here are the ONLY two things that changed in any way on my Nokia 770 since last night (when Street maps still worked fine but Satellite maps produced solid black screen):

(a) I recharged the battery overnight, and

(b) I got your reply, but couldn't try the 1.3.5 upgrade while I was at work, since I don't have a WPA key for the company's network. But I did try running maemo-mapper from the command line, foolishly..... because all that did was try to establish a connection so it could download a map, but it could not establish a connection while I was at work, so I cancelled out of the connection-attempt dialog and closed maemo-mapper.

Nothing else changed.

When I got home, I tried again, from the command line. No error messages appeared in the xterm window, whatsoever.

But guess what. Now what happens is there's no more black screen on Satellite maps, but also no more maps on Street maps! Now all I get with EITHER repository is a solid pale blue screen!!!!

I downloaded the 1.3.5 upgrade next. After that, when trying to see EITHER Street OR Satellite maps, the little message box pops up as always to say "Downloading maps", and then....this is new to 1.3.5: An error message tells me "Error in download. Check internet connection and/or map repository URL format."

However, that message only appears for an instant. I had to force it to happen a whole bunch of times, in order to be able to read all of the words in the message. Wouldn't you want to require user intervention before the message goes away? Or at least make it stay up longer so the user can read it? On the other hand, one time I did see it stay up for about five seconds. Maybe you have code which attempts to make it stay up that long? If so, that's only working rarely, here on my device.

This same error message appears in BOTH Street and Satellite maps now. And as I said, solid pale blue screen.

Well my network connection is fine. So according to the new error message, the only problem could be the URL format. But the URL format of the Street Maps repository has not changed since last night when it worked fine. And the URL format of the Satellite Maps repository, I have doublechecked and quadruple checked, it is the same as you've typed.

Tonight, out of all the folders that have been created beneath my Satellite maps "Cache Dir" directory, there are exactly three of those folders which are not empty. Those three have two files each. Last night, none of the folders had any files in them. But even though there are six files downloaded, I haven't seen a single map displayed in this repository.

The Street maps folders, of course, have tons of files because the maps have been working fine in that repository for the past couple days, and downloading everything with no problem.

Next: I was able to fix the Street maps problem after that, by simply zooming all the way out and zooming back in again, as you told me the first day I reported my first symptom. Now Street maps works fine again.

After that, Satellite maps screen is no longer pale blue! Now it's back to being black again, just like last night.

Next, here's how I fixed the Satellite maps problem: After having doublechecked my URL a zillion times....and there's no reason for you to believe me, but I swear, it was correct....but of course I could be just as wrong about that as anyone else when they all think they've doublechecked it correctly....so I visited this forum on the Nokia so that I could copy/paste the URL directly from your message. Suddenly it worked. Can it be possible that pasting it could have a different result from typing it??? I don't know how I could have doublechecked it as many times as I did, and been wrong every single time.
