If you are having trouble opening a file that you downloaded, it's probably a matter of not having a file association set up for the type of file. If you have one saved you'd like to try to get opened, post the full file name and I'll try to get it open for you.
IE = Internet Explorer (the big Blue E) and is the browser that normally comes with Windows. There are several alternatives. If you want to try one, here are links
Mozilla Firefox:
http://mozilla-firefox.todownload.com/
Chrome:
https://www.google.com/intl/en/chrome/browser/
I think either one will let you import any bookmarks that you've saved in IE. You can set any one of them to be your default browser in Internet Options. If you need further help, just post here and I or somebody else will surely help!
