How do I roll back tekkit minecraft version from 1.5.2 to 1.5.1?

my server hasn't upgraded yet and I did. I need to roll tekkit back to 1.1.7 but the choose version in the launcher isn't working?

1.1.7 is not on 1.5.1

The last version of Tekkit on 1.5.1 was 1.0.6

1.1.7 is version 1.5.2. 1.0.6 was 1.5.1

Numbers aside, I'd try uninstalling / deleting your current tekkit files, then relaunch with 1.1.7 selected. You may have to reset any custom configuration options.
