Problem rendering explode animation

Hello,

I am having trouble rending out an animation with a collapse and explode animation. When i play the animation in the soldiworks window it works just fine. However when I render out either an avi or tga sequence at the parts that are collapsing later on the in animation drop down to the origin of the assembly. Its happening on two different assemblies so I can assume its not a bug. Attached is a picture of the door stuck at the origin of the assembly.

thank you,

Bryan
