Q: I am being prompted to reactivate every time I run GibbsCAM.  How do I resolve this issue?
A:  First, locate your LicenseData folder.

Windows XP - C:\Documents and Settings\All Users\Application Data\Gibbs\GibbsCAM\LicenseData
Windows Vista and 7 - C:\Program Data\Gibbs\GibbsCAM\LicenseData

If there is a license file located in the LicenseData folder, move it to the 10.0 folder.  This should fix the activation problem.
