Got the patch installed in one player mode, no problem.
Loaded IS and started a Dual team. They both wanted to download the patch again. So I let one toon update, and mostly just read the patch file until last 50 mb or so. Got one working and then went into ISboxer and made sure they were loading same game and saved to IS. Loaded both toons again. This time worked fine. Got into the game and tried to invite and it would only say "you can't invite yourself" made a party the hard way and then tried to get one to follow the other. No go. Other key maps would show on screen but would not work like a cursor on both screens.
Anyhow, I wonder if it is in IS or could it be Jamba. Any quick fixes for now?
