Tip: If you are comfortable with RegEdit then you do not even need to uninstall FLMM in order to change mods using this method. Just rename or delete the string value for the currently activated mod in the key: HKLM\Software\Freelancer Mod Manager
If you are not comfortable with RegEdit, or have questions about the above, then just uninstall FLMM as Shockwave says.

I used to run Shattered Worlds and Crossfire mods.
First, I installed Freelancer, then Crossfire - lets say folder C:\Program Files\Microsoft Games\Freelancer. I then uninstalled FLMM.
I reinstalled FLMM, then I renamed that folder C:\Program Files\Microsoft Games\Freelancer to CF-Freelancer, reinstalled Freelancer and installed Shattered Worlds mod with FLMM. Then I deleted FLMM again.
So, to play, I just renamed both folders (SW-Freelancer or CF-Freelancer to just Freelancer, depending on which mod I wanted to play). Also, if you play singleplayer too, be careful about the savegame folders in My Documents.
With this, each mod was on a "fresh" copy of Freelancer, and there was no possibility that FLMM will mess something up when deactivating mods.
Each mod must be installed on its own Freelancer copy, no other mods beside it (like Speed Mod or something)or you'll get the cheat messages Michael mentioned and will be kicked.
