Error Code 70001

[twofuller]

After downloading and successfully installing the Home & Business version of the TurboTax software in January, I was able to create my return and have been working on it with no problems for the past 2 weekss. Until today. Now I'm getting this error 70001, I don't have multiple accounts or multiple instances of the software running on my machine.

Phone support appears to know less than even I do about this issue, and were no help. And I'm continuing to get this error when trying to open the software even after manually uninstalling, re-downloading, and re-installing.

Error 70001 occurs when you have two instances of TurboTax running.  In order to correct this error, you may need to manually uninstall and reinstall TurboTax.  If doing that does not assist, please follow the steps in this link to troubleshoot the issue.
