I never going past the first line of an error, but the way you present it, I can't help. There is always an application doing something in module ....
That can tell you something.
As for 7.0, it is way obsolete, by now, by it will do with win98.
The problem with the later programs is that they are made for people with multiple mail accounts( and ISP). I am set up with at least six ISPs.
So, if one looks at the 7.x preferences, from the browser, he will not see anything general and common settings. If you click on the mail , which has been moved to the left, or Windows|Mail., then you may be prompted to set up and account, or you can do it yourself from Edit|Mail and News.
As for what you wanted to set up, I have no idea what it is. There is an addresses.com website, which has a mail verification, but I do not see is as an ISP. However, if you had it set up in 4.x, you should be able to do it in 7.x
