emma,
Ok. You can download the scrrun.dll from any available source. The file will usually come with instructions on how to install it.
As for checking “the mail box” in Internet Options". Now a report will be prepared and you can look at it by following the path I gave you before.
It does look like OE is the problem but remember what I said about IE and OE being bundled and working together. Netscape is what is referred to as a “front end” similar to AOL. It functions as a browswer “window”. (and since Netscape is now owned by AOL, will annoy you with the same popups and ad banners. 
If you like Netscape, then why not use it for your email client?
Otherwise, we may be heading at a reinstall of OE. (Which by the way is not as easy as it sounds. )
