Hi all.

Windows XP Home SP3

I hope someone can help me out with this one:

After installing Service Pack 3, I'm getting "Windows cannot find '(null)'.
Make sure you typed the correct name correctly, and then try again. To search
for a file, click the Start button, and then click Search"
when I use the WinKey+E to open Explorer, and download torrents from
beta.legaltorrents.com from within Firefox. I don't use Internet Explorer 7
that much.
I have tried the reg key from windowsxp.mvps.org/ie/905915.htm, but that did
not help.

Can someone please give me an idea at least of what is going on with my poor
XP ;)
