Pro/E Wildfire 4 to SolidWorks 2009 SP3

The relese notes of SolidWorks 2009 SP3 tells that itsupports to open files from Pro/E Wildfire 4...

I got some files from a customer and SW says that it not a validpart file.

Have someone had the same problem?

--EDIT--
It seams like the problem lies in the export of file that comesfrom my cutomers PDM system... files I got directly from a clientwith Wildfire 4.0 it works fine.
