Tom,
1. You have been playing here for 2 years and you are still using "starter equipment" - this might explain why the ball doesn't go where you want it to go! Better equipment will yield better accuracy for you.
2. Recommend that you work on earning "Free Credits" with Videos and surveys in order to upgrade your gear - it really will make the game more enjoyable.
3. Freezing, glitchy screens have been discussed in this Forum (almost monthly) and how to solve those problems can be found using the "SEARCH" function on the right hand side of the screen.
Good Luck!
