Good to hear from you again.

One day it worked fine, the next day I can't update (and no recent Automatic Update alerts either).

So I'm sure I can reformat the SD and start from scratch, but it's a 16GB and I've got all my programs installed on it. I don't want to have to start from scratch.

Is there anything I can do? In this thread Qwerty and James talk about reformatting the internal memory card. If they mean the internal memory, cool... but if they mean the SD inside, I don't know what to do because I don't want to reformat.

Any ideas?

You need mmc1<>mmc2 clone copy, http://talk.maemo.org/showthread.php?t=29135! There is ONLY one in this universe and you are reading it...I am just joking :-).
Options
1) get a Acronis version 11 and above, back up your 16G on a PC and format your SD card and copy your backup back into the card. Remember you may NOT need to do anything on the FAT partition if they are alright, most of the time they are.
--------------------
xterm
gainroot
umount /media/mmcX (X=1 if external, behind the kick stand; X=2 if internal, next to battery)
mke2fs /dev/mmcblkXp1 (will take care of ext2 partition on your SD card, again, X=1 if external, or X=0 if internal)
--------------------------------------

you just formatted the SD ext2 partition while your FAT should remain intact, now go Acronis and do the magic.

2) Clone between mmc1<>mmc2, you do not need Acronis.
Format your ext2 partition on the SD and go http://talk.maemo.org/showthread.php?t=29135

Again, ext2 partition and FAT partition are independent from each other. Most of the time, you do NOT have to do both. I constantly backup my ext2 between mmc1 and mmc2 and it does NOT disturb my FAT partition. I backup NOT because of crash, but because I install something new and improved my tablet and I want to keep the better version. And the two SD cards do NOT have to be the same size, provided the ext2 partition on the target is equal or larger than the source, e.g., if your 16G source is partition into 13.5G/FAT and 1.7G/ext2, you only need a 2G card to do your magic.

My recommendation is option 2, it is much more convenient, once you did it, you can even make that into a command or personal launcher and do it on a regular base.

good luck
