Of course it will work. the problem is in the l4d2 .dll so if you are on l4d2, go with the sm extension by Zephyrus.
funny by the way as the orange box .dll loads up fine on l4d2 (no errors at all) but the cef.dll inside left4dead2 folder crashes the server.
I guess you shouldn't be running the ob version on l4d2 either way.
