I installed MSTS yesterday using CrossOver Games.
Install went without problems, even the changing of cd's went perfectly.
It didn't work straight away though... I got an error 'please remove the debugger and try again'. However, after updating msts to v1.2 it worked perfectly.
Today I set about installing add-ons. I went for the simplest of add-ons: an activity. Problem straightaway. About 95% of the add-on activities found on the net are packaged in an .apk-file. With MSTS comes an unpacking utility called TSunpack to unpack these files. But it doesn't work with CXG. Tried double-cliking the apk-file but CXG gave me error: Failed to open package.
In windows you could also drag the apk-file over the tsunpack.exe, so I thought I'd try that, but it also doesn't work.
Any MSTS-ers using CXG found a way to install activities?
