Vista - please advise??

i have media centre on my pc and downloaded vista beta 2 from microsoft to
test out. I downloaded the 32 bit version and began the upgrade. after
installing fine it took me to the start page with my name in a flower box,
and it was then my mouse and keyboard would not work, the mouse would not
move over the box for me to click it??

I have a logitech cordless keyboard and mouse and do not use the software on
my pc and they connect automatically, should i install the software so that
vista can recognize my keyboard and mouse?? As soon as I did the reformat and
put media centre back my keyboard and mouse worked just fine

anyone else have this problem?? any advise??
