Oh gad.
I have just upgraded to windows 7, and now, when I go to compile a new cave project for the first time, I get the following message:
"A project work directory cannot be created."
I am sure that this is an issue with windows- I did not have it with XP, but the same issue seems to exist with Vista and win7.
I have done the following, make sure that the project folder that all the files are in is not read-only, and makes sure that my user has all the required permissions. (I don't have all permissions except for the block that says "special permissions" under the file properties/security tab.
Any ideas?
