Plex Crashing

My Plex is still constantly crashing and is completely unreliable. if i can get to a show it will play fine but the issue is it will crash to the tivo menu while browsing through the list. I have two plex severs on my network and it will crash the same way on the bolt only no matter what server i connect too. I have 3 minis, two roamio pro's and plex is working ok on all of them. Does anyone have any ideas on what i can do to try and resolve the issue
