I am getting these error messages in a pop up when I try to launch anything that uses the Alexander-TW exe:

'rometw-alx.exe -mod:eb -noalexander -show_err_movie_cam ' failed (error 5: access is denied.)
and:
Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item.


I get the first when I try to launch Europa Barbarorum (it will launch if I change the exe to RTW or BI, but I want to continue my years long campaign)
The second happens with the base Alexander-TW game as well as Alexander Total Overhaul.
RTW, BI and the Invasio Barbarorum mod for BI all launch just fine. The game is installed directly on the C drive

Any help would be appreciated.
