Autovera errors in Vera log file

I have found errors in the log file relating (I think) to autovera. Any idea what they are and why they come up ? One of the tablets does not exist any more, but i cannot delet it from my Autovera device (When i open settings its stuck on opening showsettings). Could that be causing the errors ? Reason i am trying to find the cause is some of my devices are very slow to react so trying to repair all the errors i can find in my logs and see if that helps.
