PHT not launching in HD Station

this just started a couple of days ago. I’ve rolled back firmware on my NAS to .4.3.4.0486. I also rolled back PMS software. when I click on Plex in HD station I get a spinning wheel for a few seconds but nothing happens. PMS launches fine in chrome in HD station. The QNAP version of PHT sucks as there is no recording or program guide - does anyone make another player for QNAP. Is there a Plex Media Player app for QNAP?
