Open part from assembly, what i am doing wrong?

Hey fellas, I am beginning with the SW API. My name is Richard. I've been programming a macro to help me to rename assemblies and each part from they. Everything was well until I opened a part (.sldprt) from the assembly. It works (the document opens) but there is an error message that says: "Object doesnt support this property or method".

This message only appears when I use "Part.OpenCompFile" to open a part (*.sldprt) I dont have any problem with the assemblies (*.sldasm). On the other hand, I've tried to use the "opendoc6" but it does not work.

The code is the following... what am I doing wrong? Thanks!

Excuse me if there are some incongruities on the code. In red and blue some notes about my problem.
