About 4 months ago i got the trial of reason 11 and it worked fine. Then this last Sunday the 7th I went and bought reason 11 intro for 100$.
Every time i try to load the Reason Rack Plugin i get an Error, Write Problem, and it will not load. I sent Reason a Support Message Sunday and they have not replied yet. Ive tried many things. Ive tried totally uninstalling Reason and reinstalling it + Deleting all reason registry keys. I've tried giving my whole C:\ write permissions to "Everyone". I've tried Reason 11.3, 11.2, 11.1, and 11.0 all the same problem. I don't know what the problem is. It does this in FL studio 20 and I own a app called Midi Guitar 2 which can load vsts and i get the same error. The actual Reason Daw will load fine but trying to load the Reason Rack Plugin in 2 different vst hosts i have gave the same exact error. I also sent a message to Image-Line and they said to message Reason because it was an error coming from Reason not FL, which I did but have not gotten a reply in now a week.

There's a truthful answer to that question... which will not be the one provided over at RT.cj31387 wrote: Sat Jun 13, 2020 11:21 am I don't know why reason doesn't have their own forum. I just posted in ReasonTalk though. Seems to have a lot more users there. Thanks
Have you tried Vital?
