Cant join multiplayer.

[DamoX]

First off I want to say sorry if this is the wrong forum for this, if it is mods feel free to move.

 

Here is my issue, I cant JOIN the service, every time I do it says invalid serial, I have never once used a pirated copy of this game on my computer(I'm a hard-core sim guy from the 90's....I've bought -every- module for this game even though I suck at all of them).

 

I've double checked my login and password, the dcs module manager showed me as valid for all the stuff I have bought and I can play it all.

 

Where do I start troubleshooting this?

Thanks!
