Unfortunately, I can't help with Launcher issues. I haven't yet figured out how to even get it to load on Linux. If you post in the Launcher Thread
, I bet Quirinus can get it working for you next time he's logged in (he wrote the thing). There's also a tech support channel on MXL's Discord
you may want to check out, if Discord's your thing.
Otherwise, I'll do what I can here to try and walk you through an install via D2SE, if you want to go that route and if you have a version of D2 1.13c or lower (digital copies purchased from Blizzard are janky af).
