I have used the Addon Builder to ages, went on vacation, when I came back I get "Error on Steam Initialization" and it closes automatically every time I try to start Addon Builder. Every other tools in DayZ tools is working fine, only the Addon Builder is giving me this error. I can't find anything online to help with this. Can anyone please advise? I have uninstalled tools, uninstalled ALL games, and uninstalled everything including Steam itself and reinstalled after each. Still the same error.
