2.0.2. Cant get the Plugin to work like it Should.

Good morning Everybody.
I would like to get the last Video Updates from an Youtube Channel.
So if i use the Videofeed Type: uploaded by a user, i get the following Error Message: Message from server: . Check in YouTube if the id IGNentertainment belongs to a user. To locate the id of your user check the FAQ of the plugin.

Any idea what i should do to make this work?
