Custom Beaglebone

Hi at all,
I want start to modificate and customized the Beaglebone PCB, but I
have intalled Cadence 16.2, and I can't open the beaglebone files with
this version of Allegro.

I have used this PCB version of beaglebone :

http://beagleboard.org/hardware/design

But I can't open the PCB proyect with allegro.
Somebody could help me to export this proyect to 16.2 of Cadence version.

I have altium too, but when I import this files to Altium have a lot
of problems with some regions of PCB.

Thank you in advance.

Contact me direct and I will see if I can help you or not…
