Might as well start a new [Suspicious link removed]d luck getting yobit to fix the wallet or update it. Their support takes weeks if not months to reply if they ever do.
XBY had the same issue with wallets disabled or under maintenance, basically their keeping your coins hostage.
that is why we have the swap and after that we can just ask yobit to close old wallet and add new as new coin
its better to revive old coin and help investors make return on what they lost instead of making new
