my money balance is suddenly became zero !!!!!!!
here is a screenshot as a proof, it became zero for no reason, i remember i had 17 !
Hi, this only proofs that you don't have any bank balance and not that you didn't buy any players.
Which you have done today and yesterday.
If you buy more and you don't get enough income from selling players then it's possible that you are at zero now.
So you have to sell players, to create more income.
