You need Freelancer MOd Manager - it's pretty darned effective, and if you're messing your game files due to trying to make mods - you can make them inside FLMM (as in inside it's mods folder that is, create a folder of your mod name and then recreate the files that are necessary (as in you're modding) inside there as if it was inside the Freelancer folder, so for example - a freelancer.ini file would need a new sub folder called exe, and then pasted inside of there. A new goods.ini would require a new data folder, with a new equipment folder as a sub folder of datafolder - into which you paste (and then edit) your goods.ini file. Hope that helps).
