If you find out how can you let us know so we can tell other people? Don't suppose you have an online account you can log into from when you upgraded? Oh and did you buy the CD from Amazon or the Download? You probably will have trouble installing from a CD again and need to call in for that too.
Here's an old note I found, If you upgraded to a higher version or bought extra states they should be in your Turbo Tax account downloads, or you will need to ask support for them again,
