You could try IEradicator click here , but as it says "Not for use with Windows 2000sr2 or Windows XP " . Some people have had problems after using it so remember to back up your data beforehand if you do decide to use it. The site recomends you read the text file before running the software click here .
I have e-mailed you from the website with a link to a repair tool. The e-mail was returned as not able to deliver. Have you changed your e-mail address since you registered? If so e-mail me from the site and I will e-mail again with the repair tool link. It is a very long address and you could easily make a mistake if you try to type it.
