I installed the free trial and ran it this morning, it took it a few seconds and it had indexed 472 pages. I liked it so much I purchased the product. Downloaded it and installed basically overwriting the previous install on my site.
Well the difference in performance and results is remarkable; the purchased version indexed less than 200 pages in an hour and even though I have deleted it totally and re-installed it keeps getting worse.
I have never tried the trial version of a product and then get the real deal and it does not perform the same. There has to be an explanation for this odd behavior; it makes me wonder if the trial version and the purchased version are the same products.
