Is deleting appcache folder advisable
I am trying to run Bioshock, I have windows 7. Initially I followed all the advice given regarding compatibility mode and sound mix etc and it worked fine for a while. Now I just get error saying it is already running and when I click on the link steam provides it advisors me to delete appcache folder but there seems to be a lot of stuff in there, will it cause problems with other games or is it a safe thing to do? Advice please.
