Code downloads with errors

I'm new to Web Dumper but can see it's potential. I purchased it yesterday after a short trial because I needed to save a customers website before moving it to a new host.

Unfortunately the source code contains errors even though I selected too rebuild the local paths. As an example

Should read

<img width="900" height="173" src="wp-content/themes/impact/images/logo.png" webstripperwas="" >

But Web Dumper gets
<img width="900" height="173" src=

Not only is it missing the link but the path "impact" becomes "impac"
