my wallet stopped syncing. Reinstalled with new version and 0-1 connection with nodes from this page

ERROR: mempool transaction missing input
in logfile
Did you update as in the guide on the zeitcoin site? You need to completley uninstall the old ZEIT folder (obviously backing up your wallet.dat first), then install new version. Put your wallet.dat file back. If it does not synch afterwards, delete everything except the wallet.dat, peers.dat and zeitcoin.conf.
yes I did. my post above is after those manipulations
