You could always try uninstalling the software and installing a clean version to see if that helps.  I ended up dong that a month or two ago after I couldn't get into the program.  But this late in the year, you might want to lick your wounds and keep on fighting with it a little longer.

As a side note, I tried to e-file a few returns yesterday and when I would try to open an individual client I would get the message "please wait while Windows configures Quickbooks".  It opened up business returns just fine but I would have to hit "cancel" three or four times before I could open an individual client.  Some days I really hate Inuit.  Well, ok, I hate Intuit everyday but some days are worser than others.
