I contacted YoBit about the same problem.
****"Deposit\Withdrawal coin will be available after you upgrade the source code of the wallet. Unfortunately the developers are in no hurry to send you updates
If you have updated the source code of the coin, send us (https://yobit.net/en/maintenance_request/ Free)and we will promptly correct the problem on the coin."****
If you know how to do that then maybe we can help each other. Cheers.
