Get your taxes done using TurboTax

I am in the middle of a return and can't access it because I lost my activation code.  I can't even access the completed returns saved as PDF's on my desktop.  Turbo tax say since I purchased from a retailer they cannot help me.  It seems crazy that I will need to purchase another 80.00 program to finish up this return.  I have the folder the CD came in but not the activation code which I tore off and probably threw away.  HELP
