Can't switch to 3.1.3?

[WarpZone]

I am using Technic Launcher 1.1.2.0. I want to play on a whitelisted 3.1.3 server I was recently accepted into. When I click Options, then click Manual Build Selection, then select 3.1.3|1.2.5|Latest , then click Login, it says "Update failed!"

How do I connect to a 3.1.3 server?

In case the answer involves updating the launcher: My friend tells me that the latest tekkit launcher no longer allows you to even select which build to use, so I'm not going to update the launcher unless somebody can tell me what version of Tekkit Classic the new launcher uses.

And why is there only a *beta* launcher available from http://www.technicpack.net/download? You don't force a beta build on your players! You provide a stable build and a beta build and let the players make the choice of which one to run.
