Hello,

Nope, Windows 8 shouldn't make any difference, I am also running that.

What favourites, if any, do you have set up in Internet Explorer? Looks like one of these is not a valid URL. It looks like you have identified a bug in the application though :-)

For now, again, what is the value of sb.ToString() when the exception occurs? If you set a breakpoint on this line, you should be able to figure this out. Are you familiar with how to do this?
