I have a similar problem with a just purchased license for BitDefender Total Security 2011 ((3 PCs , 1 year)). When I am asked for the License No. at the beginning of the installation it is accepted and I get a congratulations message. In the final part of the installation, I recieve and Invalid License Key message and when I attempt to re-enter, I receive a message that my license is for BitDefender Total Security Online Backup. Would you like to install this product instead?
Could you please help me with this issue?
