MP startup problem-please help!

[unmerged(3742)]

A friend and I have gone through a weeks-long hassle in order to get EU and be able to play online, I even had to upgrade my computer just for EU! Now when we're finally ready it isn't working properly. When I host a game it works for me but he can't join. The first time we tried it nothing happened and the program stopped responding. Then he tried again a few minutes later and it worked, we played for a few hours without a hitch during gameplay and decided to meet again today. However, every time he tries to join the game that I've hosted his computer sounds like it's loading something but doesn't do anything and after CTRL+ALT+DEL he realises that the program has stopped responding. He can still play single player just fine, but are the minimum requirements for MP play higher than single (more RAM maybe)? Also,I don't understand why it worked perfectly that one time but all other attempts have failed. Please Help Us as we are getting really frustrated with this.

I suggest reading a few of the threads on this forum and see if the suggested fixes work for you too =)

I have tried reading all the messages about mp problems but while there are a lot of them I haven't seen one with this exact problem. I've read plently about failing to load saved games in mp and a 'no host game detected at this IP address' problem but none so far that discuss the program freezing as a player tries to join a mp game. Maybe I've missed some so I'll re-check the threads but I'm fairly certain that the answer to my question is not found on these boards yet.
