If a customer wishes to run previous versions, with an upgraded key, they have the opportunity to do so. The key is backward compatible. Simply uninstall the latest revision and install the earlier version. However, the earlier version has to be compatible with the Windows operating system you are running. If a customer's temporary codes expire, due to an extended delay in shipping a replaced key, we will extend the temporary codes in good faith and issue permanent codes once the key is received. An email notification has been issued to this customer and a reply was received back--acknowledging its receipt. If a reader has any concerns it is recommended that they contact EZ-CAM direct.
