Multiple Arma 2 instances on steam version

[vindaboner 10]

Hi guys,

Search for this didn't find anything current

I ran a headless client scenario. Prior to the switch to steam (post BattleEye) one could run multiple Arma 2 instances with a server by using a reg key switch for the cd key. Post the patch relating to the BattleEye shutdown, I'm unable to get the second instance to connect to the server, presumably due to a cd key issue.

Just wondering if anyone has a workaround for this?

Many thanks,
