Cortex asking for access code

My cortex was initialy giving me some problems. When I turned it on, the lights would go red as if the batteries where dead, but I changed batteries and the problem continued. After this, I tried turning on the cortex while holding the configuration button. It seemed like progress, but after I downloaded the master code, it started to tell me that it needs a new acces code. Where can I get one?


The access code message appears when the ID on your Cortex becomes corrupted/invalid.
In order to restore such ID you will need to obtain an access code & new ID from VEX, please duplicate the error message again and call us directly while the message is still on your screen.

For more information about access codes please read pages 6&7 of the PDF file posted here.
