SPC stands for Special Project Code. Several years ago, PERRLA replaced this purchase mechanism with newer technology that we call Promotional Codes.
If you have a valid SPC that you believe entitles you to our software, please contact our Customer Support team via email at: firstname.lastname@example.org
Be sure to include your SPC code in your email and let us know where you obtained it. We'll look it up in our system to see if it's still valid.
If so, we'll provide you with a Promotional Code and instructions on how to redeem it.
