I had a similar issue today after changing theatre from Balkans back to KTO to match Falcon Lounge server. After joining online it would get to “Receiving Units” and go no further. Didn’t CTD so i could exit but standard KTO single player campaign’s were greyed out and i could not start a new campaign. Switching theatres again had no effect on KTO.
Only way for me to fix was to uninstall and reinstall 4.34. I figured something was broken in the KTO theatre and only way i could reinstall KTO was to redo whole program.
