Okay couple of things:
-
The Movie matching logic had a bug which is why the movies never worked, I've fixed that (KungFu) in the next BETA Release (03112013)
One of them - I Survived , the series information does not exist in thetvdb.com -
The rest 2 are working fine for me, I'm able to download the information (Walaking Dead and Bearing Sea Gold). I suspect it's a problem with your internet connection, you, if you're constantly seeing this then your connect is intermittent nad MCEBuddy is not able to connect to it
