I just found out that if you might be experiencing problems with G2's Multiplayer feature. In the G2's EVENT section, Jim Coleman states that with the first release of G2 software there might be a bug, or something on that line.
Anyway he also states they have a fix for it, Just go to your G2's CONTROL PANEL to download the latest updates for the fix. So if anyone checked out my other post ( Having Problems with multiplayer anyone? ) Try this fix first, if for some reason your still having problems after getting this fix. Then I guess it's back to reporting the bug to the ( Report Bugs ) section. But it sounds like this fix will do the trick.
