Made a testing mission in FMB and i found out that i cant save any mission or play it .
when i click save as, writing name and blablabla.. save and nothing happens, when i check the saved missions folder ,theres no mission saved .
I click play and same thing , nothing happens.
I can load other missions but i cant start them from FMB .
Any ideas? :?
