Upgrading from the C4 Engine
If you ever purchased a non-institutional C4 Engine license, we will deduct the regular single-user price of your old license from the cost of a new Tombstone Engine license. Please enter your license number (beginning with C4T) and the email address used on your old account below to get the discount. This offer ends on May 31, 2017.
