Car won't start after tune change

I've had my predator turner now for 5 yrs. Today I changed the tune on my car and now it won't start. Turn the key and all lights come on and also the message center says ABS failure, fuel gauge, failure, and on and on.

When I tried restoring the stock tune, it wouldn't allow it saying something about unauthorized because download tune didn't match car or some stupid thing. When I attempted to redo the performance tune it asked me whether my car was a SSR or Trailblazer SS (it's a '06 Impala SS). I didn't want to choose either for fear of something getting even more jacked up.

whats the revision on that tool?

does the tool try to restore the stock tune when it boots up now?

Thanks

It boot up like normal and when I try to install factory tune, it brings says p/n can't be found. Then shows ssr and trailblazer ss
