For the convenience of our users we allow for up to TWO simultaneous installs on separate computers. This means that you may install one copy of FaceFilter 3 on two separate computers without issue providing only one computer is in use at any one time. It seems that after the crash it is seeing this as another install and is trying to activate again.

To resolve the problem you can manually deactivate the license from one of the two computers you currently have activated. Please follow the steps on the FAQ below to deactivate your license. Once you do this you will be able to use FaceFilter 3 again.
