Ableton Forum

I have installed this version and I was using normally. Today it doesn't lauch. I've tried to delete all thigs related to ableton, including files on /Library/Application Support and /Library/Preferences and install the software again. But the problem persisted.

So I discoreved the VerifyPermissions Software at Ableton, but when I install my software again, thouse Application Support and Preferences files are not created again. So the VerifyPermissions can't do anything. How can I fix this?

Thanks for any help,

Robson.
