I've had MC 22 on my iMac for almost 2 months, and I still can't get it to run right. Every time I go to open it, it wants to reinstall the software, and won't work unless I do. Doing this creates multiple MC's on my toolbar. Also, about 4 of them keep opening and disappearing at the bottom of my toolbar, plus the other 2 solid ones that don't quite work. Sometimes I can get it to play music, sometimes I can't. It quits unexpectedly probably a couple times an hour. It's driving me crazy, and at this point, I'd rather just switch the license to my PC, but apparently the licenses aren't compatible. UGH! Any ideas?
