I actually reloaded SiteImport 300 on another laptop -- I did this because, I never had any issue with SiteImport 300. It worked and I am able to get the site imported.
Well -- I will delete SiteImport 3.0.2 from my development laptop and then reload it back and see if I am still getting the same error. I have to say that prior to this one time, I have never experienced any error with 3.0.2 other than it seems rather slow. Actually, I will try and import a different site and see if I will get the error. Nonetheless -- I will romove 3.0.2 and then re-install it -- then I will see how it works afterward.
