Thanks OP for answering, I was hoping the very same issue you told me in your post, so basically its going to be a big head pain, all this crashed append in versions 4.17 and 4.20, in 4-20 its worts because you dont start on mahanttan and the game CTD when you dock even on a trade lane, you may or may not pass 1 or 2 tradelanes and then pufff, on 4-17 got campaing screwed afther saving a research station from rehynald military assault, afther that, ctd if you try to fly to california minor or when undock from the rescued research station, but weel, that didont matters for now, the file Content-0C458F.dll i downloaded i just unpack it on DLL folder and then the Flserver.exe begins to work instead Ctd afther several second, i noticed this afther switching to console view in flserver.exe. Well, now i going whit the good news, i was blessed by all lucky goddnes on the universe, and i still dont belive it, but afther some hours searching on google, whit very old and litte sites abd by changing a bit the search query, i got WTS 4-16 server pack files, and afther the 3rd and last site matching my query, a working instace, the first 2 where corrupted and cannot unpack, the sited was 1/3 english 2/3 russian, whit i dont understod a single word, but the files are ok, enable me to SP play and mount a Lan server, well, need 1st to make a virtual machine to run the server, FL didont like to connect on the same machine hoting the server, but whatever, whit all of this, i think, 1 of my 1st post is fixed, mount a basic wts working what lets you play, the mergin option, whiele still begin complicated, whit those files i suppouse it could be now done, at least for SP campaing. Right now in a few days i not going too be hable to connect because RL issues, but i like to give it a try to merging or try to fix version 4-20, i dunno, this things time to time are fun for me instead of playing, i m not a programer or coder, but sometimes its fun triying to understood/learn how stuff works. Can i have permision to do a litte project to mergin both? at least the content, ships equipment ect, i need to know what tools i need to get 1st, also whould you like to have me upoad the wts 4-16 server pack files or post a link whit the file so you people got acces to it to add to your download page if you wish, of course. Well this post its getting very long XD. I be back when i can. Thanks for the reply, will try out the edit you tell me in freelancer.ini on both cases if applicable, MP and SP and see if fix anithing or have to get dirt my hands in a IDE or notepad+.
