Now I know everyone is having problems with starting up their game, some is only just their multiplayer and some are both campaign and multiplayer.
This one worked for me and it probably won't work for everyone but just give it a go.
- Firstly watch this YouTube link: HOW TO FIX configure_mp.csv: exe_err_couldnt_connfigure - YouTube
- Then go down to the description and it will have a link to a download file of players2. You need to download that and if you don't have Win zip or Winrar you need to download that too for it too work.
- Then follow what the YouTube video says, so copy the file into your players2 file.
- make sure you delete your files you had in it before you copy the other ones in.
- Then open up multiplayer and it will say something like 'Your game did not close down properly, would you like it to start up in SAFE MODE?' say no and then a few more will come up. Say no to them. If the game doesn't start up maybe try and say yes to the ones after the Safe mode one and see how that goes. If it doesn't work at all i am sorry but I tried to help.
GOOD LUCK!
