1. Apple Care is generally useless in that fashion.
2. M$ has, apparently, a problem with fonts. After searching online, one site recommended opening Font Book and discarding any "bad" fonts. This I did . . . voila!. Also make sure you have the latest update of, I assume, Office 2008.
But this does not help you! I HOPE you back your data up to an Ex-HD. If you do not then retify this error in judgment, character, and musical tastes NOW.
I will wait.

You back? Good! Nothing solves "Frelled Beyond All Hope" like a simple back up from an inexpensive Ex-HD. When you fix the problem, you will back up your system. In fact, you will partition the Ex-HD and back up your 10.5 AND 10.6! Any you will be happy and cease buying Hanna Montana albums!
Now, to me, "Kernal Panic" usually means a hardware failure, but I SUSPECT you have had a problem with frelling your System. So, I think you have no choice if you do NOT have your data back to boot on your Installation Disks and try to repair what you can. Otherwise Archive and Install again, BACK UP your data, and start over.
IF you have DiskWarrior--which is STILL very useful--that might fix things or at least make a copy of your disk to save data. TechTools also works but it just does not fix things the way DW can. However, in the future, with a clone of your drive you will avoid such problems.
Hope this helps!
