Many months ago I loaded my AutoCad Lt 2004 on my secondary computer. I believe I'm following the rules, because both computers are only used by me and I can only use one at a time (they're at different locations). For the first couple times (on the secondary machine) I just cancelled the registration option when I loaded up the program. Then I didn't use that computer for the longest time. Now, several months later I went to use my AutoCad on the secondary computer and I got the prompt screen telling me that I needed to Register or Authorize my program with the Authorization code. So I dug out my Authorization code and hit the button to continue. The 'Register Today' box pops up and then the whole program simply freezes. Nothing ever loads in the 'Register Today' box. It simply starts to load up and then poof....AutoCad hangs!! I have to do the ctrl-alt-delete to exit the program. I've re-booted, re-installed, and re-you name it......nothing!!! It still hangs-up at the same point every time. Does anyone know why this is happening? What can I do to fix it? Thanks, Lyle
