Sad that you don't get CF running .
For an 'enhanced' storyline mod that is ... challanging maybe try this one : https://swat-portal.com/forum/…gDaddy-Storyline-mod-1-2/
But be warned : it IS hard to play and already the first missions will need quite some time. Try to exploit whatever the FL-engine gives you for opportunities, i.e. the 'zones' around a mission point, where npcs attack you and other stuff. Maybe one of the bigger differences to vanilla - and Crossfire - the 'defense' focus is way more on shileds in this mod than on hull strengh.
If I remember correctly there is - at least was - the possibility to play this mods : http://www.moddb.com/mods/wts-world-ccn and this one : MD's Freelancer Rebalance mod - Mod DB
also in SP campaign mode. (easlier versions where this might still be so are to be found in our FileBase )
But they were RLY easy to play and in campaign mode not much of a challange due to the access to added stuff .... and both have a damn awfull LOT of stuff added
