I was using FD v 1.10.173 which is a patch to v 1.10.169. I uninstalled it (the program only, not the snaps) in order to install v 3.20.202. And that wouldn't recognize any number I put in the validation box so I quit that. Then I went back to reinstall 1.10.169 and it won't accept anything I have for a validation key. From Raxco I have a password with 10 characters in it and it didn't work. I had another 7 characters from the "about" drop down menu in FD. That didn't work either. I have an order number and a customer number from Raxco when I renewed FDISR and PD for 2 years taking me to July 2008. None of these numbers work. Without FD installed I can't boot to any of the snapshots I have. Checked my email all the way back to 2004 when I first purchased FD and can't find anything calling itself a license number. Is this something simple or do I have to deal with Raxco support? Edit: I do have one ace. I have a 2 day old ATI image to resort to. But that's not going to solve the issue of not being able to uninstall/reinstall FDISR.
