AC2 direct x8.1 or higher error

Seems this error is back when logging in multiple clients for me anyway. Was working great then on next computer reboot not working.

I can log in each client separately without IS running fine.

I got around the resizing issue by sizing all clients one at a time separately while not running IS. I stack the two slaves on second comp screen and video feeds etc work great.

Love this program but isn't working right now due to this error.

Found solution on a previous post.

Please delete.

What was your solution?
Or can you link to the thread where it was found?

Someone might find your issue, when they google yours...
Having the solution would be nice.

The problem is created by having the clients in windowed mode, full screen does fine.
