Unfortunately I don't have much control over the system that authorizes the items if there are problems. Nothing in the game has changed in a long while. Sorry that you ended up paying twice, but MochiCoins ensured that their system would continue to work even if the in-game login is gone so you should not of had to purchase twice. Eventually I will probably make the upgrades unlocked for all users since this micro-transaction systems have been nothing but a headache and I have been getting very poor support from them.
For MochiCoins re-authorization you need to go to mochigames.com and login.
For GamerSafe re-authorization try logging out and clearing your cache then try logging back in.
