When the client can update the client, the client version of the current I can not use a variety of methods can be synchronized (such as adding nodes method), I can only use the page wallet 

hmmm, for me it work with out any issue.., do you put the nodes in the conf file ? and what if you try to clean your J blockchain folder ( I mean try to remove the peers.dat, and all the .log files from the folder (stop the wallet before that), there to be the conf. file, the wallet.dat, and the folder with the blockchain) So leave in the folder only: (FOLDERS):"blocks", "chainstate", "onion" and "tor" ; (FILES): "joincoin.conf" and "wallet.dat" . Also remove everything else from there
DON'T FORGET TO COPY AND BACK UP YOUR WALLET.DAT FILE
