As long as the route is installed in TS10, you don't need a FCT to transfer it. Simply select the route in CMP, save as cdp, then import the cdp into TS12's CMP.
It would be a good idea to register your copy of TS12 as well. You can do that by following the link at the top of the page.
Depending on how you bought your FCT it might take a little while for it to become available for you to activate.
