License code has already been utilized
If you do a fresh install of Marked 2 and receive the error "License code has already been utilized" when entering your license, please contact me requesting a new license. Please include the email address you registered under and/or your current license code.
Early licenses generated for Marked had a usage limit instead of a machine limit, so 3 installs---even on the same machine---would use up activations. These limits have been corrected in more recently-generated licenses. Purchase of a Marked 2 license permits you to install Marked 2 on any machine you own, so don't hesitate to ask for a replacement if you run into issues.
