my bad, I wasn't aware there's a new wallet version already. I just update last night to 4.0.2, left it overnight to sync.
My wallet staking 24/7 so I dont know about newest version when I wake up and I check wallet 05/01 to vote I saw vote window and I vote for SeGwit but dont know about relase again newest wallet version.
And now I saw too: Warning: Unknown block versions being mined! It's possible unknown rules are in effect ...
Timing was wrong on 4.0.2... updating to 4.0.2.1 is just closing wallet, downloading new version and starting it.
That's it. 5 mins tops
