Hi!

I'm playing Baldur's Gate 1 (EE) with another person in multiplayer, but after a while, we start getting problems. The person I've invited keeps being disconnected with no apparent reason (I'm the host): I gain control of her characters and she gets booted out of the game. She can reconnect, but then she gets disconnected again a few minutes later. We have disabled all anti-viruses and we play in LAN, so I have no idea what's causing this issue.
We were excited to start playing this game together, but sadly it's basically unplayable. Any help will be greatly appreciated.

What game version are each of you using? v2.5.17.0 (last 32-bit build) or one of the recent 64-bit builds? If yes, which one? Are both of you using the same build number? Are there no error messages shown on the guest's system? Does her game crash to desktop, or dump her to the multiplayer join lobby?

We are both playing with the 2.6.6.0 build. And no, no error messages, she just gets booted to the multiplayer menu.

EDIT: I don't think it counts as an error message, but she gets something in the lines of "disconnected from the game", but nothing other than that
