Magic Article Rewriter/Submitter

I bought the Magic Article Rewriter/Submitter combo and on the surface it looks like good software. I have two questions and hopefully those who have used it can respond:

1. What is considered to be a 'good' number of accepted registrations at the article directories? I tried twice to do the automated registrations and only ended up with about 250 out of 700+ directories. While this is still alot of directories I'm wondering if some of the directories in the list are outdated or are blocking somehow.

Any tips to increase registration acceptance? I filled out every field in the profile, and I tried multiple times to go through and have the software 'read' and verify activation links in my gmail account I setup (IMAP is enable). Didn't seem to increase the registered accounts on the directories.

How many valid registrations is everyone else getting. And from that how many of your articles are being accepted?

2. When I do a preview of my 'spun' article before submitting it shows the same article variation over and over, even with the spin syntax in the title, body, etc. Will it automatically submit different versions when I submit to the directories? I haven't tried submitting yet because I'm hoping to increase the amount of registered directories first.

Thanks!
