I've been trying to run the Demo of this game from Crossover. it won't get past the loading screen, and the demo's log shows this error message:

I've been corresponding with the game's developer, and he thinks the problem is a lack of permissions to delete files within the game's folder at Steam/steampapps/common/.  Any ideas?  I tried setting R/W permissions in the game folder to "everyone" from OS X but it didn't help.
