vanguard not found : VGExtreme Requests

When I run more than one copy of Vanguard on my computer I get an error message: Vanguard was not found. Please restart when it is running.

How can I fix this?

i was reading around and it seems like people have been having trouble running two windows?

maybe this is new with the new update but I just run two clients by running the patcher twice.

just to clarify incase this is a new option with the recent patches.

I dont run 2 copies under the same machine sO i really cant help there.
