Hi Jaice,
Sorry for the delay in getting back to you on this. We have now updated your account to be linked to your new Steam profile (
steamcommunity.com/profiles/76561198279935232). All your upgrades will now continue to work as normal on this new Steam profile. If you are currently connected to one of our servers, you will need to re-connect for these changes to take effect.
Thanks for supporting ZARP!
