Terminal Service Plus

I am getting an error message that the IME editor does not match.
We updated 1 server to the latest to get around logon issues dealing with Microsoft patches etc.
Now users are getting this error message when being load balanced to the patched server.
Is there any way to suppress this error message until we patch the rest of the server ?

When logging on directly to server we do not get this error message, only when being load balanced and assigned to the particular server that was patched.

Hello,

something went wrong during update.
Do please following steps
1. logoff all active users except your self
2. reinstall update
3. reboot your server (that is mandatory step and can't be skipped)

Sincerely yours, JW.
