Have you checked your internet connection?
After several attempts, I got in.
Wallet is not good enough.
Wallet is developed on Counterparty platform...Counterparty is not good enough,too old and only a few active nodes . Footballcoin wallet is the best Counterparty wallet as a UI/UX.
I think it'll be much better if they'll develop their own blockchain/wallet with low fees and fast confirmation.
Bitcoin and Ethereum faced a lot of technical problems last months and very high cost with tx-fees.
Anyway in-game market it was a very important improvement of the game and it'll help a lot with global adoption of the game.
