System Error after Annihilus Install

[Iridius]

Updated - no worries fixed it now.

Hey guys,

So i'm running Win8, I downloaded and installed Diablo 2 + Expansion legitimately from Blizzard. After I install Annihilus I click on the Annihilus Launcher and get the following error message.

420

Any help would be appreciated.

Regards.

I see you got it fixed! That's good because I have never seen that message before, lol
