BAML Error When Animating

I have the following code in a WPF 4 project, linked to an imagebox. I have four other similar instances of it that work perfectly. Why is this one throwing that vague "BAML" error we all hate (it points to the animations)? FYI, I'm using VB.net in code behind.

KeyTime="0:0:60" and Duration="0:0:60" do not exist, the seconds range is from 0 to 59 only, change those to 0:1:0.
