File associations
 

My file associations were just reset, and I can't change them back. (all the boxes, menus, etc, are greyed out)

Anybody have a clue? please?

*mumbles*
I never had problems like this before I upgraded to SP2....

Is this a work PC?

What OS?

Have you tried right clicking on a file and "opening with?"

Might've corrupted your user account, if this is WinXP. Happened to me, not sure how. My user account (Documents and Settings, etc..) got corrupted, and all file associations for that account were borked. Created a new user, moved all the settings over, and voila. May or may not work, take it with a grain of salt.
