Hi Joaco16. Thanks a lot for your fast reply.
I finished the first season and wanted to try the first chapter of the second one. I opened the game (MedievalTimes_Chap_10.exe) and tried to enter the code for the first chapter, but I was able to enter just the first 6 letters, the rest did not fit any more. I am playing on Win10 obviously.
It was just a trial. I am waiting for the last chapter of the first season anyway :) I want to be ready, however... Thank you in advance!
