I was getting all kinds of errors the last two days. TurboTax would not update or even startup. After a manual update and calls to Intuit I had to uninstall TurboTax and reinstall it. My data file was retained so I didn't have to start over but what a pain. The program worked just fine in April, hadn't been used or updated and failed to start yesterday. Why the software became corrupted when not in use I couldn't tell you. You may have to do the same.
