Hi, I’m trying to evaluate EZDRUMMER 2 (DEMO VERSION) but after instaling, and trying to open, the EZ always, I mean, ALWAYS shut down. Its appear for few seconds open then shut down. There is no way to make it work! I’ve tried everything for 2 days, reinstalling stuff and get the newest OSX version, the YOSIMITE. and reinstal, clean up my MAC fot older versions, try outs, etc but nothing working. This occurs at my home MAC and my job place MAC…I’m really disapointed, can you folks help me out to figure out whats is happening? Thanks
