Trouble getting all 4 screens to launch

I have been boxing for awhile, but ever since the patch came, i couldn't launch even one screen. I did some trouble shooting and now can get the first to load, but it just loads as if i was playing the game normally on one account. So if anyone can help, it would be much appreciated, thanks!! Note, i have tried both skip and not skip launcher and i also have the settings to allow multiple instances....so there it is, please help....

We probably need this:

I have the same problem except I only dual box. The first account logs in perfectly fine but the second doesn't allow the blizzard toolbar to update the patch and I get this error - Error: BLZBNTAGT00000871

Please help I have been trying to figure this crap out for hours by unistalling and reinstalling everything and nothing is working.

This doesn't sound like the same problem as the OP, please don't hijack his thread. If you're using the launcher, then you need to skip it.
