I would, however, recommend just doing another clean install of Freelancer and FLMM
Follow the below instructions which I copied from another thread. I didn’t use CCleaner and I was fine, but if you want to be 100% sure, go ahead and use it:
Removal of Crossfire 1.81/2:
1. Go to your Control Panel(CP) and uninstall Freelancer and the Crossfire Mod.
2. Go to your My Documents and delete the Freelancer Folder.
3. Go to the folder which contained the Freelancer game and delete it, because it remains after the uninstalling from the CP.
4. Go to your Freelancer Mod Manager, and you'll see 2 uninstall exe files. Use them both, use the first one and then the second one, as they are placed in the perfect order. Once this is done, the 2nd exe you've just used will delete the whole FLMM and its folder automatically.
5. Use a Cleaner program, such as Advanced System Care(better in this case though..) or CCleaner.
6. Remove your remaining iso files within the Daemon Tools or Alcohol 120%/52%.
Installation of Crossfire 1.82:
1. Install Freelancer
2. Restart your PC(The Setup wll request it when it finishes with the installation process).
3. If you're running Windows Vista or 7, after the installation , right click on the FL Icon/Properties, compatibility and then choose " Run it Under Windows XP SP3". , you can also change your FL icon from there too.
4. Install Freelancer Mod Manager 1.31(FLMM)
5. Install Crossfire 1.82 ==> Both Freelancer Mod Manager and its mod(CF) must be in 1 same folder. (As the CF Mod installs within the FLMM program).
6. Activate Crossfire 1.82 => In the process of your activation, you will notice that the windown will go to a " Not Responding " mode ... => ignore that and keep waiting until it activates it. It requires several minutes.
7. Once that's finished, if you're planning to play in the Crossfire MP ( or even CF SP) , wait for the updates to download and then click CF SP/MP button to play.
Just make sure that when you are activating the mod, you select the correct options for OpenSP, which i believe is what you want. I just downloaded the mod last week and I have been thoroughly enjoying going through the campaign again in this environment.
