I am a complete idiot - I thought I had got CP up to date, but I hadn't. I can't believe I missed something so obvious :(

I deleted the data directory and cloned CP from GitHub. Now it works perfectly with NZB 360 v8.4.3.

For reference, my CP version is now 75a8529 (17/7/2014 21:24:48) git, master

Sorry for all the hassle guys.

I'm getting the same error too. Am running the github version detailed below

Version 75a8529c99996a0ba20fdcf83d424b6597bc3f8

Anyone else still having the same issue? Am running v8.4.3 of NZB360
