After I installed OpenXcom, and the nightly build, I just get this error window every time it starts. The log inside the Xcom directory says ' [ERROR] neither UFO or TFTD data was detected', although I have a steam version of XCOM which I have also copied to the desktop to try and fix the issue.
The log in my documents gives a little bit more information:
[05-07-2015 19:01:30] [INFO] Mapping resource files...
[05-07-2015 19:01:30] [ERROR] cannot determine current active master
[05-07-2015 19:01:30] [INFO] mapping resources in: common
[05-07-2015 19:01:31] [FATAL] Failed to open directory: common
Any ideas what is going wrong and how to fix it?
