An issue has been identified that effects the Mac App Store editions of our titles running on Mac OS X 10.6 and 10.7 systems. The problem only occurs under user accounts with the FileVault enabled.
Launching the application results in the following error message:
Unable to create folder ‘User:Application Support:EdAlive:V2combo’
Unfortunately this is an incompatibility with the FileVault that we cannot currently fix. However, a work around would be to create another user account that does not have the FileVault enabled. Alternatively return the software to the place of purchase and obtain a refund.
