Error 1502

I posted this also on the forums. I hope this is not a breach of 
etiquette but I am kind of desperate.

I upgraded my Mantis installation from 1.1.6 to 1.2.5 yesterday. Here's 
what I did:

1) I backed up all code and data
2) I deleted all code
3) I uploaded new Mantis Code
4) I uploaded configuration files from the 1.1.6 install
5) I ran admin\install.php. It told me everything was fine
6) I logged in to the system with my regular user id (not my admin uid)
7) I got the error 1502, Category not found.

I get the same error when I log in as administrator.

I am DOWN right now and cannot proceed. I have checked the bug logs and 
I have not really seen a fix for this. All the items I have seen talk 
about moving something from one project to another which is not the case 
here. They also ask me to login to the system which I cannot do (or 
rather, I can log in but I never get to any page I can work from!)

Any assistance would be GREATLY appreciated.

Thanks in advance!
