THIS WORKED!
Thank you SNA for mentioning this. I plugged in a thumb drive (the same one I keep all my saved tax docs) and tried to open TT cd version and it said "enter activtion code".
I almost passed out having spent hours on my return and ready to finally file. I ejected my 4GB USB thumb drive
and it retried opening TT, it opened up perfectly, phew!
Thanks for posting this for a quick fix!
