Internet Explorer cannot download

Hi there,

Recently, my website has been acting up in Internet Explorer. However, it seems to have gotten a lot worse, and now when I try to access the page, it attempts to download the index page, and then presents the following error:

Internet Explorer cannot download / from http://www.dot-totally.co.uk.

Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later.

I didn’t realise at first, since I use Firefox mainly, but since it can’t even be accessed in Internet Explorer, its quite annoying. Firefox states its being served as “text/html”, but Internet Explorer seems to be ignoring that and attempts to download. Has anyone had similar problems or know of a fix to this? Thank you very much in advance!

PS: Although the link has a period on the end, this is just where the error message sentence stops, I am not attempting to access an invalid URL.
