I rented a putter and played a bit. A few hours later, I tried to play again and got the message that my rental period expired and to update my equipment. When I tried to drag the standard putter into the bag, I get an Unexpected Error message. I have tried replaying the game, restarting the browser, and even restarting my system. Unfortunately, the error persists. Consequently, the game is now unplayable. Any ideas?
