There was a bug in motion sketch. Have you updated AE.
Also, motion sketch only records data in X and Y so the motion may not translate to a 3D layer as expected.
It is hard to know if there are other problems that an update may fix because you didn't give us any system details, project details, or tell us what version of AE you are using.
Provide the exact error and the details Rick requested. Those numbers by themselves are pretty meaningless and the text of the message may in fact already point to the culprit.
