I use IX
I use IXwebhosting and have used the UR solution pack successfully quite a few times.
The only solution I can think of is that you need to put your server information for all of the lines (verification, registration, and password email settings). Oh, and the .ws ending is not something I am familiar with but that doesn't look right. You may need to post a ticket.
Your Email Server should be something like: mail.yoursitename.com
Your Root_URL should be: www.yoursitename.com/
Your Email_From (on all three email settings) should be: firstname.lastname@example.org
