they have servers up now, And you can play both BHD&TS
they have different Icons to show the BHD&TS servers.
You cant see them in this link, But here is the new link just to have a look.

Just Make sure you have updated and all should be fine. I dont know if you have to update both to V1.5.0 as they both have updates out.
