I just registered to say I had this exact problem this morning. I downloaded the latest demo yesterday, and fired it up this morning before going to work (I’d not got on with it last time I tried, about a year ago, but I found the videos on the wiki very informative this time).
Anyway, once it came to scan the plugins, it hung my entire machine 😯 when it got to the FL Studio (7) multi-out VST. I was going to have another go tonight with all of the FL VSTs moved elsewhere, as I want to give Podium a good try, but I don’t have a problem with them anywhere else.
I hope this helps.
Michael.
