Crossfire Mod Launcher and Updater
Try this launcher version, first clean install of mod, before you start the first time then replace the files and then start. I am not sure about E7, either its an error code from the old launcher (1.9) i dont remember to have had such codes before - so i assume its still 1.9 launcher. Which it shouldnt in first place.
I don't think it's 1.9, because, I have after month Freelancer reinstallt, then the Mod Manger+ Mod, activate the mod, becomming this problem.
Edit: With the newer one you write about to try it, it now work for me. Thanks. (Y)
