Another way to ensure you have a good backup is to keep a safe copy of the folder "My RoboForm Data". If you ever have to re-install, just copy back the contents of this folder and everything is back the way it was. I keep a copy on a external hardrive and on a thumbdrive.
FYI, I select a range of passcards as well, and can do as many as 15 before the world starts to slow down. It is good to keep the simple and complex entries in different folders, as sometimes when I don't have much time, I just zip through the simple ones.
