I had to uninstall EMC10 because it didn't work. Since EMC10 deletes EMC9, I attempted to re-install EMC9. I got the bad key thing resolved. Now, it gets about 90% through the EMC9 reinstallation, and a message comes up that says: "Please insert the disk". The install disk is already in there. I tried the Content disk but that didn't work. Then I put the install disk back in and that doesn't work. So, what disk is it asking for? (After taking 20 minutes to get to this point, I then have to wait another 15 mins while it backs out of the install). Dick K.
