Hang in there dude. I was made master in the big update and went from a 68 Pro to a 75 Master within 2-3 weeks. All good now and back to a 65 ave. Has taken me a good while but my game is back on track and i'm loving it more than i ever did.
I understand your annoyance, but as the lads have said, new tee boxes, new distances for approaches etc etc. Trust me when i say that in a couple of weeks you will be back in the 60's in ave and you'll be enjoying the game more so than you ever did.
