I'm bad with programs

[NonKhaos]

Hi all, I'm trying to use sandboxie to play multiple clients for a online game, my only problem is that I have no idea how to do this, When I'm in sandboxie, i choose to runa program and i choose my games launcher but the launcher doesnt connect to the servers but if i do it outside of the sandboxie program I have no problem. Can anyone at least point me in the right direction?
