NextPVR Service Stopping

I am using Krypton beta 5 and whenever I try to change the channel on one of my client PCs, NextPVR stop working on my server and I receive the addon not working error message. It works fine after I restart the service on my server. I am using the latest NextPvR. Any idea of what is going on? Everything was working fine until I upgraded to Beta 4 and Beta 5 didn’t fix it. I am work and if I need to upload a log I will when I get home this evening.
