Major problem with Temporary Internet Files

[Supafly345]

My temporary internet files won't store anything. When I try to increase the amount of space to use for storing them from 0mb (I don't know how it got there) it tells me to "please choose a number from 1 to 0mb." Which I cannot do. It won't let me change the location of the internet files, and when I try it says "Not enough space in destinated folder for current files." I know it isn't a disk space thing because I have over 11 gigs left.

Restart didn't help. I am running on XP and I only started having this problem yesterday when I tried making the "local settings" folder in "owner's documents" visible. Whats happening?
