I am having the same issue.  I am a small accounting/bookkeeping firm with over 40 clients.  Every time I open the software I have to go through numerous crashes and till I can get one to stick.  Often times even when it stays open, it’s a frozen screen if I navigate towards payroll, I then have to control alt delete to shutdown, and start the process over.  I have rebooted, uninstalled - installed, file doctor ect - no results.  I came here for the 5th time looking for help.  I am now on the 5 reboot for a file that will not stay open for more than 1 minute.  I am beyond frustrated.
