Invalid File

Apr 4, 2009
I entered half of my logbook entries last night. I got up this morning to start entering more. When I click on the logbook pro icon, the home page pops up with another window that says INVALID FILE try again, but it freezes up. Please help so I didn't waste 4 hours of typing last night.

Try clicking Start...Programs...Logbook Pro and launch Logbook Pro from there. I'm not sure exactly what you're clicking that ends up with the error message you're describing.

If the problem remains try reinstalling Logbook Pro. Uninstall it from the Windows Control Panel and then download the latest from our web site and reinstall it. Data and Registrations are NOT affected by reinstall.
