That was the solution! Thank you! I tried chmod 766, and that didn't work, it needs to be 777. 

I actually can't even log in on the terminal. I have Caché installed on Linux, and when I run "sudo csession UppercaseCache"  on the terminal, I get the following message:

How do I log on as a Privileged User? 

I set it to minimal when I installed it, but accidentally (I'm a new to cache and all) removed the %All role from UnknownUser which was the user my log on defaulted to.
