I can make the xml files and then it says they were uploaded, but the link to see the FTP content just shows 0 in there

If i log in with my FTP client i cant see any files in there

It goes to processing in Base, for an hour or so and then say that there are no products...

I think this is because i am using Simple SEO URLS?

The file that is uploaded has the NEW rewrittedn URLS!

Is that correct... if using SSU should i be uploading the original URLS or the SEO urls?
