Don't see a problem with witnesses, you have 2 witnesses properly configured, right?

yes 2 on it with active key i will up then what he make but he never starts :( staying now on 98%

Eventually it should finish with the rescan of the blockchain and start mining... just stick to clean shutdowns to avoid the extra wait.

You know that with two witnesses rewards will go to both accounts, right?
