Thanks for the reply, I tried to run the DX version but got an error message saying that the d3dx9_38.dll file is missing, so, I googled it, found and downloaded it and installed it into C:\Windows\SysWOW64, the programme still wouldn't start (same error message), so I copied the file into C:\Windows\System32, now I get an error message saying that The application was unable to start correctly (0x000007b).
The GL version works.
What am I missing?
thanks in advance
