Incorrect key file for table usercss

[RedDevil]

Thanks for the info i did read through, its supposed to repair all databases on upgrade, but for some reason, all 3 VB4 databases have the same corrupt error all on same table, which is weird.

I can create a new DB and export and import the offending tables but on a site with 18,000 members im reluctant to just do it without making sure its not going to do any major harm, seems this covers custom profiles so wont be a biggy, was hoping maybe someone encountered tis and knew best cure.

The error is also preventing a database backup as it wont go past the corrupt table.
