Help, Connection issues

Hello,

I just bought this game and it's awesome, but there is a big problem when I try to play with my pals. Sometimes the game just crashes when someone is connecting to me and when I try to connect to his game my friend crashes.

From time to time it does work but it seems too big of a problem for a proper enjoyment.

Its quite frustrating when we can't manage to play because everytime one of us try to host the game freezes and crashes eventually.  with a big

I just masked ID, IP and stuff but the port is the one from the log: 0. when I see that it seems kinda weird. 

Well, I hope there's a solution, I'd find it quite sad if I had to pray to a god for luck everytime I try to host.

My config is:

Windows 7 Ultimate x64

i7 2600k @4.4Ghz

16Gb DDR3 @1800Mhz

256 Gb SATA3 SSD 

580GTX

PS: I don't know if it changes anything but when the game crashes it does seem to erase my stardock password.

PPS: Oh and I have big sound lags.

Happy Holydays everyone
