No, that didn't work either.
I had to sign into my IE homepage, plus my usual and regular sites.
No doubt it will be something really small and obvious - but I am blind to it.
This also happened when I was running IE7 Beta and decided, because of its problems, uninstalled and went back to IE6.
The minor annoyances, that I personally had with IE7 Beta, seem to have been ironed out - but it is little things like my cookies being eaten by the cookie monster really gets to me.
Maybe I should get my ten-year-old nephew to look at my pc when I get back to the UK - he will sort it!!
