I backed up my Quicken 2000 for Windows file today and when I tried to reopen it, Quicken shuts down. Neither the original nor the file backed up opens. I am able to open other Quicken 2000 files—just not the one I backed up. Yet, when I open Quicken 2006 for Windows on a different computer and convert the backed-up file, which didn't open in Quicken 2000, it successfully converts and I can use it. Does anyone have suggestions for why I have that problem and any solutions?
