Of course I used MC's uninstall procedure!
But I currently have issues upgrading to Studio One 3.3 (crash on start!) which came out a few days ago and digging into the issue this came up in the log file of Studio One:
"...
2016/08/26 18:17:01.064 [Warning] (asioservice): UID conflict on class registration: JRiver Media Center 21 (AudioDevice ASIO)
..."
So either MC 22 uses a wrong version number (currently I have 22.0.21 installed) and it should be "JRiver Media Center 22" or there are remains of 21 left on my system. The other thing is the UID conflict which looks suspicious.
And ideas, hints, suggestions?
