Reply to Licensing question when re-installing Traktor and OS

I know with traktor you get two licenses. A few weeks back I had to uninstall traktor and then reinstall it on the same computer (mac) will NI class that as I have now used two licenses?

The reason I ask is because I have just got an SSD and would like to fully reinstall lion (fresh install). Will I run into any issues installing traktor again? I have it on cd from when I purchased traktor scratch pro 2.

Any info would be appreciated. Cheers.
