With Win RAR you can check the files to insure they are ok.
Now without knowing where in the install that this message shows -Its really hard to say what to do.
If it was at the end of the install and you have the REAPIR and UPDATE
icon on your desk top.
You could try using that. Nothing to lose.
If that does not work then I would say you need to redownload the UP.

ANYONE ELSE HAVE ANY IDEAS?????
