2nd window of 5 not working - WoW

I didn't put a subject and my post didn't show up after hitting submit so I'll try this again.

I used to box 5 characters and am trying to see if my current computer can handle it but when I start it up, all the windows load except for number 2. Even if I try to open it separately from the rest, it doesn't work even though the others do. I used the setup wizard to create the team. Any suggestions?

Thanks.

You can open up the Inner Space console (right click IS tray icon > console) to see what is happening when you launch that particular Slot. You may have selected a game/game profile which doesn't exist by accident, and if that's the case, then you will have to adjust that character in ISBoxer to the correct one (upper left pane choose the Character > lower right pane adjust the game and game profile).

I shut my computer down to get some updates and now it's working but thanks for the quick reply.
