Norton 2014 Anti-Virus Program Installation

I purchased Norton 2014 Anti-Virus program for 3 pc's about 6 weeks ago.  Yesterday I had a problem with the Live Update part of the program where the updated definition files would not install.  I tried to manually run the Live Update feature but got a message that said failed to complete.  The tech representative told me to uninstall the program, run the Norton Removal Tool and then re-install the program.  That solved the problem but what I'm unhappy about is that I now only have 1 installation left instead of 2.  Norton counted 2 installations for the same computer.  I don't thin that is right.
