I had BitDefender 2008 and when the subscription ran out I renewed and was trying to install 2011 but I am getting the error "Cabinet file bdprof.cab for this installation is corrupt and cannot be used. This could indicate a network error, an error reading from the CD Rom, or a problem with this package." This is a home installation using Windows XP Professional and IE 8. I have uninstalled BD 2008, rebooted my PC and attempted the install twice and continue to get this error. I also remember having problems with 2008 install so hopefully someone can help since I have paid for a product I am unable to use. Thank you.
