Can't Install or Remove Anything

[benoldcrap]

This is a new one to me. As of today, I am unable to install anything on my phone. I have plenty of memory. When I try to install anything...even things already on my phone, it gives me a prompt of "Installation of xapplication was unsuccessful." This comes up before I would normally be asked for an installation location (storage card, main memory, etc.).

When I go to remove programs, the program box is blank. I can still access and use all of the programs that I have installed, but nothing is listed as being installed. Even in Active Sync, it only lists the programs that I had previously installed through AS, and trying to uninstall with AS does nothing.

The last thing I was able to install today was FTouchFlo, but I don't know how that would've done anything like this.

Soft resets do nothing to improve the situation, and I'd really prefer to not hard reset if I don't have to because I stupidly haven't done a backup in a while. Any suggestions??
