Hello.
No metter which type of script I try to write, when I hit the compile button I get a window with this message: Unable to write source to temporary location. This happens with the most basic scripts, such as GetOwningQuest().SetStage(10) and such. I tried to google it with no luck, I've seen people having this problem but no solution can be found. And yes, I tried verifying files and reinstalling the CK.
