Now I know it must be good if they actually sold you on the upgrade Vikki.

You have held strong on version 4 and proved you could still keep up without all those following upgrades.
I believe you should still be considered as an upgrade and only pay the upgrade price. Be prepared for a bit of a learning curve since things have changed quite a bit from 4. Can't wait to hear how it goes for you. Don't forget to give us a play by play when you get it.
