Have you tried the link in the OP (https://bitcointalksearch.org/topic/qora-pos-assets-names-polls-automated-transactions-social-network-1358722)? I've had no problems running the wallet on 64bit linux. There is a log4j error (mentioned several times in the last few pages) at start up, but I ignore it with no problems. Been running the wallet for months with no problem.
Or use OpenLedger.
Or sell at 2 sat asap. Imo the price will continue down. You will be able to buy back cheaper if you want.
