Mainstage: Registry Error
Have bought Mainstage 3 to run a live set with click, backing tracks and keys patches, but on opening, Mainstage is freezing, "not responding" and when force quit, there is an error message behind the loading screen that says "registry error: please make sure the product is properly installed" I have reinstalled from the app store three times now with no results. I;ve also tried downloading a blank concert preset and opening from there with the same issue. It crashes when it reached "updating information about Audio Plug Ins"
Any help would be really appreciated, It's a shame, I used to use mainstage years ago at Uni and it was amazing then.
