Hi, I have just purchased WOFF BH&H II, following all the instructions found in the help PDF, including installing direct x 9 using the file in the toolbox directory. However when I attempt to start a mission, I get an error appear in a messagebox: ------ EXCEPTION ------------- Patch ID 'rexDllNameString': data to be patched does not match ---------------------------------------- I then get another error message box appear from CFS3: ------ Combat Flight Simulator 3 --- Unable to check EULA. ----------------------------------------------------- I've searched around and I can't find anything related to this issue - in fact searching google for "rexDllNameString" reveals no results My anti-virus has not interfered with the installation or program itself. I am using Windows 10 64 bit   Do you know of what might cause this issue, and what I might be able to fix it?   Thanks
