I'm honestly not sure as I don't have/use Adobe Premiere. I am mostly stopping development with the original StrokesPlus and moving on to StrokesPlus.net. If you wouldn't mind, give it a try just to see if it works in Adobe Premiere:
If it doesn't, I'll want to dig into that to see if I can find out the cause. I have a lot more options as a developer within StrokesPlus.net to debug issues than I do in StrokesPlus.
I decided not to download the new software since its still in beta, and all of a sudden strokeplus has started working in premiere without a problem :))
