Mabye this topic is a little bit out of date, but i had same problem now, and this solution worked just fine. Ive just copied plugin from Program files/adobe/common and paste it to the CC directory, but didnt delete it from previous dir. Ive louch premiere and error has occurred, that MB didnt run properly, so ive deleted plugin from CC directory and now its working fine from previous directory. So victory! Its working again. Sorry, for my bad english skills, but i hope it will help somebody elese with this annoying problem. Cheers!
