No problem with anything else at all, been running keyclone fine up until tonight.
Can run 3 instances of WoW fine with KC nps, but once the 4th loads thats it KC crashes
Will run a Disk Check now, while I go to bed
I may go for a reinstall of vista as for some reason it has bloated itself out to 50gb and I can't see where all that has come from.

If I re-install will I still be able to use KC on fresh install or will I need new key?
