So error 33 is no communication on CAN2 - which is the connection of the TCU to the ECU.
If you have loaded a new file and the error just occured, try opening the new file in tuner pro and select compare then load bin. Put the previous file into Bin 1 and hit ok.
Then go to tools and select the difference tool, check the limit search to defined items only box and hit search. If you see a difference on CAN2 settings you'll need to transfer them over to the new file.

Just found out that the plug from my 6hp is different to the one provided from turbolamik 6hp to 8hp apparently my f02 has a different return towards can lines coming from tcu
