Nokia :: 5530 Camera Stopped Launching / Tried Reset

So, my camera stopped launching. I fixed this yesterday by backing up my contacts and bookmarks and doing a reset (*#7370#).But then I noticed a few MORE issues with the phone that didn't exist before.

1. File manager. I can't copy files from one folder in my memory card to another. when i attempt this, the file manager spontaneously shuts down and redirects me to the main menu.Also, I can't seem to install any files on my phone. I'll start the installation, i'll accept the terms of agreement, i'll press continue... and then NOTHING. It just sits at the screen showing the .sis file i was trying to install. but nothing happens. i can't even delete the file b/c it says it's in use.

2. Image editor. i can edit images, but when i try and save them, the editor just closes and takes me to the image gallery. No saved image.

3. software update. the software update shows me a list of available updates like adobe flash lite, ovi contacts, shazam etc. I'll select a file to update, say for example, adobe flashlite.It'll say downloadin adobe flashlite (1 of 1) but the progress bar just WONT progress! it stays empty!

4. Settings>application manager>installation files.this will show an installation file for one theme that ...i'm not even sure i have on my phone anymore! at least, i can't find it on my memory card ( which is where it's supposed to be)which is strange, since i have a bunch of other installation files on my memory card which aren't showing up at all.it's perplexing. they should have a seperate forum dedicated to issues with the 5530, given the amount of trouble one has with it.

oh, i forgot the mention, my firmware is very much up to date. it was up to date before i performed the reset.but i updated it again last night, just in case that'd fix the issues above.it didnt.
