I can play the courses (I'm not sure if I can play all of them) but when I try to submit my score the game crashes. Any ideas?

I would try to delete GL Golf off your iPhone and re-downlaod it (no charge, same with all in app purchases except the mulligans), that has helped some users get around this bug, which I still cannot consistently re-create.

I deleted and re downloaded and the scores can be recorded. BUT, now iTune shuts off after a couple of shots. What's up with this. I had to repay for some extra holes and still don't have all that I had before.

Email me your email used to purchase the game and I'll send you the most up to date serial number that has all of your courses. Are you pressing the m key by accident? That would turn off the music.
