Preserving old links when importing articles via RSS

Hi there,

I’m having trouble importing a large RSS file into WordPress (1000 complete artilces), using the recommended RSS Import tool.

Even though the <link> I want to preserve is specified in the XML file, WP simply adds its default URL, e.g. ?p=6 URL at the end.

All the rest of the content is imported perfectly.

Any ideas how I can preserve the current URLs on import?

Many thanks!
