So, this morning I spent a couple hours changing themes and tweaking stuff. I restarted several times during this period and everything seemed ok. I also started trying to get Winamp to work so I could use it's wireless syncing with my Android phone. Winamp wasn't working but I read a suggestion that updating WINE to version 1.3 might help.

At some point I decided to restart again, and found I was unable to get past booting in. The computer hangs and brings up the error messages Aggregation not enabled for tid because load = (different numbers, usually 0, 1 or 2). If I let it sit for fifteen minutes or so it will accumulate three or four of these messages, with occasionally different values.

There is also an error message that appears on this screen for VirtualBox but I disregarded it because on researching it it seemed that this often shows up without causing problems to people's booting up their computers.

So, the things I did that may have caused a problem:

Played around with Ubuntu Tweak
Installed a new version of Wine (1.3)
Added new ppas
Set my user to automatically mount my data storage partition on login.

Of course, I have no idea what these messages mean, so it could be something else I did that I don't realize is the problem. Let me know if you have any questions or want more info.

Thanks everyone for your help in advance. =)
