As of version 12.8028, an unlock code is required in CRE and RPE to change your current payment processor, please includes your payment processor info if unlock code is needed when you request a key.
Please download the latest 64bit full release, and the quick patch if needed.
The video here showing you 3 different subscriptions I have for pcAmerica CRE and RPE, you see the credit card unlock window in red because the unlock code entered is for that 30 years code, you will see it disappeared when running with the 30 years code.
After you have downloaded the setup file and installed, run CRE2004.exe as admin and please send email to nanfen@gmail.com, includes the security code on registration window on each POS computer, I will send you cracked key to activate offline.
