Quote from Bose321 :

I am using Z20. The server of mine is Z3. ALL version servers show 'wrong version'.

edit- Reapplied Z20, works again.

I have Z20 installed and i'm getting that exact problem right now, all servers are listed as wrong version.

Thank you all for the testing.

Now you can try Z22 which has a fast host list and new XR wheels.
