Here is the best solution I can offer as far as playing different MOD's.
Believe me I've done this literally hundreds of times and that's no exaggeration...
Delete Freelancer... Yes that's right I said delete your Freelancer folder...
Reason being...
By deleting Freelancer instead of reinstalling you make sure that no files get left from the previous MOD especially dll files, they will crash Freelancer in a heartbeat.
Sometimes files get left behind by the uninstall routine...it happens take my word for it, so it's best to just delete your Freelancer folder and then reinstall Freelancer...
By Default Freelancer gets installed to >
C:\Program Files\Microsoft Games\Freelancer
Delete that folder...
Next >
Delete any saved games... Yes that's right delete or move any files in the saved games folders... Saved games can cause a crash too...So they have to go...
Your saved games are located at >
My Documents\My Games\Freelancer\Accts\Multiplayer\Singleplayer
Delete or move any files in those 2 folders...Clean out the folder but you can leave the folders there, just get rid of the files inside of those 2 folders.
Multiplayer and Singleplayer
Next >
Pop in the Freelancer disk and install Freelancer again...
Next > This is optional but I don't hurt any...
Download and install the
The Freelancer SDK v1.3 The SDK (software development kit) is a self installing exe file, so you shouldn't have any problems installing it...
Now install the MOD in the
Freelancer Mod Manager v1.31 and activate the mod you want to use by double left clicking on the Mod file, they all have the extension flmod.
It should be working now...
If it still don't work uninstall the Mod Manager and then reinstall the Mod Manager...The Mod Manager comes with an uninstaller...
If it's still not working leave another message and someone can come up with the right answers...
