Hello,
My wallet is out of sync from may be 25 hours. I do not understand why ?!
I have HTRC Masternode and status is Active, but no coin and out of sync of my wallet.
I had the same problem yesterday. Make copy of your wallet.dat, than delete everything exept wallet.dat and Backups folder and run your wallet again. It will start sinc from beginning.
Thank you very much. It works now.
