I've followed the Crossfire Installation Instructions in the tutorial as closely as I could, but I'm coming up with this error during activation in the Mod Manager:
2506 files restored and 0 directories deleted
Error: problem activating 'Crossfire Mod 1.81 Client Edition'
Error: SHCopyFile failed ('C:\Program Files\Freelancer Mod Manager\mods\Crossfire1.81\EXE\MSINET.OCX' to 'C:\Program Files\Microsoft Games\Freelancer\EXE\MSINET.OCX')
Hope to hear from one of the experienced fellas around here. Many thanks.
Edit: I seem to have solved the problem by running FLMM v1.3 as Administrator.
