Quicken crashes, hangs or loops
at startup?

Please
try this:

* Reboot Windows.
* Close Quicken (or do not
     start it at all).
* Use Windows File Explorer to
     locate and rename your current Quicken data file. For example, if it's
     called Qdata.QDF rename it to QdataX.QDF

          Usually your file is located in your
     C:\Users\_your_username_\Documents\Quicken folder.
* Having done that start
     Quicken as usual from the Start Menu or Desktop Quicken icon.

          If Quicken cannot find your current data file during startup it
     should just simply load the program and give you either a nearly blank
     menu screen or one that has options to start as new user, restore from
     backup, etc.

* If you get to this point
     without Quicken crashing 
* click on File in the Menu
      bar. Select the Validate function. Select the renamed Quicken data file
      and see if Quicken can access and repair it.
* If the data file is beyond
      repair, try to restore your data file from the most recent Manual or
      Automatic backup. Go back to restoring successively older backups until
      you find a file that works
