Get your taxes done using TurboTax

I followed the instructions and deleted the files and reinstalled and emptied the trash again.  I got the same error again so I rebooted and was able to successfully get turbo tax to open.  However when I clicked on File/open recent and tried to pull in the file that I started a few weeks ago, I got the error message that said it shut down unexpectedly.  Do you think my old file (that I was almost finished) is corrupt somehow?  Do I need to start all over again?  If so, should I just use the on-line version instead of loading it to my computer?  I have never had this much trouble before.  Thanks for you help.
