I have the CD version, latest patch 1.61b
playing with no CD key
several custom changes
I also have an unmodified secured copy of myFHSW folder which I choosed to switch of the customisation but nothing works
Playing for 1 year with these settings without any probs on FHSW europ server
disabled the virtual drive and using the CD ... still didn´t work
map FHT Prokhorovka is in the right folder and path
Also I can play it if I open a game at home.
