that's with plain wine and not staging? It's still not working for me on 2.4 staging.
I actually am using 2.4 Staging. But ya know, I actually remembered I was trying to get StarCraft 1's PTR working all day the other day and one of the things I tried was manually updating the Battle.net Agent. Try it out and tell me if it works.
