Hi, I've just downloaded the trial and the first 3 times I tried to start the software it got through the loading screen and then stopped responding. Checking the Console app I saw the following line:

23/07/2014 10:50:08.892 gkbisd[244]: Unable to collect cdhash for /Applications/Spine Trial/Spine Trial.app (error code -67028)

The 4th time it worked.

Also Mac OSX tries to stop the user running the .pkg installer as it's from an "unknown developer"
