I want to update my Tekkit to version 3.0.3 but I cant figure out how. When I start it up it is version 1.1 rather than 1.2.5. I read the on the Technic pack website that said " Currently Tekkit 3.0.3 is technically a beta, and as such you must manually select “3.0.3| 1.2.5 | Latest” to connect to a Tekkit 3 server." How do I manually select verson 3.0.3?
