I tried to purchase some gems from the in game shop to buy some keys but it keeps showing an error message when i try to open paypal, not sure if others are having this problem, I tried restarting the game and using a different character to buy them and tried doing it with card all to no avail. Would really like to get those keys and those cat ears, thanks for any help you can offer. --------UPDATE--------- Just reloaded the game after leaving it off for a while and it accepted the codes I had.
