I assume you've checked the obvious things like typos and whether or not the licenses have actually expired? Are you sure that you also have the right version for your device type and that you've selected the correct Emulation Type?
Just adding on to what Matt said...
Authorization Code Check failed!
This message comes up when the information is not entered exactly as provided. Everything has to be the same including Licensee Name, Platform, Serial number, expiration date, user limit and the authorization code. Remember there are no numbers on the Authorization code, only lowercase and uppercase letters.
If you have checked and confirmed the above please contact support for further assistance.
