2010 Network Game Help

Trying to set up a network game with an edited database with a friend, basically I edited all the database, saved the DBC file in my SI documents folder, default path. I then sent him the same file, he saved it in the default path too.

So the game loads up fine offline and as a server for me, all the data is there edited as it should be. Every time he tries to connect he gets an error message and FM10 crashes out. I had these problems with previous versions of the game but they always were fixed after we all had the common data files but that's clearly not fixing it this time.

As a side note I've connected fine with a PC on the same network in my house... No idea if that helps at all.

So how can I fix this and actually get to play my game with my friend?

The error message would most likely help, I am guessing all your ports are open that are needed for FM and your both playing on the same Patch...etc....

Can't see the error message, he said it flashes up really quickly then the game crashes and quits before he could read it.
