Why won't my Sidekick 08 scroll anywhere/respond?

I was going through my phone and I happened to have changed the language. It asked me to restart so I can activate the new language on my phone, which I did re-activate it, and it turns on, but now it's not letting me scroll anywhere, and it won't respond to any of the buttons I'm pushing (although it only restarts using 1+@+0, the restart button in the back, and simply just taking the battery out). How can I get it to work?
