...work anymore!

I uninstalled, deleted anything I could find in iFile, reinstalled, still doesn't work. The app loads, but it doesn't work. It's enabled in the app, and enabled in in SBsettings, but when I get a text, it's the original method of texting that sucks! And in the app if I set the compose method to double tap the status to compose, it just starts the app.

What do I do?
