Support has suggested several ways to try. Yes, I have tried from the Z3tA UI as standalone and as a VST while occupying a track on 2 different DAW's - Ableton and Cakewalk by Bandlab. I get the same result. On Cakewalk's site, where you submit the .crq file seems to upload just fine, but nothing comes back. From what the instructions state, is that I am to expect a .dat file that is suppose to automatically upload to me. But nothing comes down, I've tried through Chrome and Edge.
Could be on the server side, iisreset maybe?
