Yes, I was referring to that one ... but you fixed it anyways :-)
I deliberately deleted the folder .maps because I thought it would interfere with mounting the image file to that directory.
Btw., how can I see that everything worked and .maps is a mounted file instead of an ordinary folder?

And one other thing: Now that everything probably works as expected I cannot access MyDocs via USB any more. Only my SD card gets mounted on my windows machine :-(
Apart from that I'm very happy that people like you come up with crazy ideas ;-)
