i havent even bothered with mm15 for ages as it was doing my head in, but i had an email today saying i had new answers to the above post, even though there are some from ages ago!!
i may try what the guy has suggested on there to see if it works
I was trawling through this forum trying to find out why I also have the VST plug-in problem. I found a lot of the same question with no answer that worked! Somehow the Vita works for me but the Revo does not.
OK - another update: after you install that patch I mentioned below, I've now been told that I have to uninstall MM15 Premium and reinstall, and it should all work fine including Revo files. Quite frankly I'm too scared to try. Anyone else want to give it a go?
