Please Help Me, 3 Days & Still Nothing!

Hi People,

This is my last hope, I've scoured the internet, top to bottom, asked around. Nothing.

Here is my problem:

I have a MAC, my friend has a PC.
We want to play a network game of Football Manager 2010.

Ok, So in order to do this, your supposed to download Hamachi, and create a virtual network, you both join and you can then play the network game together, if only it were that simple!!

Thing is, when I connect to him, my name on his list appears with a yellow triangle, with a ! in it. Advising of an error, something to do with a tunnel error, or VPN Error I think it was.

Is this issue caused with me being on Mac and him PC?

How can we resolve this?

Please help!

Have you tried creating a network using your mac's inbuilt feature, and then joining that with the PC?

No, I havn't.

I'm not particularly sure how to do it either, sorry for my lack of knowledge.

If you could explain, I'd be grateful and give it a go.
