6.5 upgrade to 7 registration query


I have a query on registration and thought someone on here might be able to shed some light?

Basically I upgraded from 6.5 to 7, when it asked me to register when first starting up I pressed ok and It took me through to the e-licenser bit, I entered the code it asked for and it said that the e-licenser was already registered.

Now when I look on the registration section of the website it still says that 6.5 is still registered.

Im very confused! Does this mean that the 6.5 registration still works for 7? Or is this going to cause me grief further down the line?

Any advice much appreciated!
