Description
Sorry, the key file you saved has expired or the contents you inputted were incorrect. Please try it again. If you want to evaluate Foxit PhantomPDF, please press the Cancel button.
Reason and Solution
The Activation box doesn't allow any blank spaces at the beginning and end of the registration code. If there are spaces before/after the key code, the button label next the Cancel will show as Install the Key -- this is incorrect and will give an expired error message. The correct label is Next -- that is the way to the successfully activate the registration key.
