First close Turbo Lister and then locate the Update directory on your hard drive. For Windows 8, look in the following location:
C:\Program Data\eBay\Turbo Lister2\Update
If you don't see the Program Data folder, you may need to change the folder settings to show hidden folders. In Windows Explorer, click the Organize menu. Select "folder and search options." Click the View tab and be sure that "Show hidden files and folders" is selected; then click "OK."
Delete all files in the Update directory so it is empty. Then launch Turbo Lister and check for program updates (Tools > Check for Program Updates).
The above information is from an old Turbo Lister response by an employee at Ebay, not me. Hopefully it will work for you.
