I tried searching for a solution to this, but no luck. Hope I don't ask a trivial question, after checking the FAQ.
My friend and me are trying to play RA3 co-op. We both have the game from Steam. We manage to get to the briefing screen, and then hit play on the mission. The load screen appears. My friend always goes to 100% (even on his end) and I get stuck at 96% (last time he said it was something in the 60% range maybe on his end), then after a few seconds, I get this screen:
He gets a black screen. Neither of us can interact with the game any further, and it has to be killed from the task manager.
It does not matter who hosts, it's always the same. We tried the first Allied and Soviet maps, to the exact same result every time.
We can both play in single player without issues.
Help would be greatly appreciated.
