Hi Eriberto,
This is really strange, I can't figure out what os going on... Did you got the issue just after installing CopperLan 1.4(2)? Are you sure that you did not install other hardware/software?
Did you try disconnecting all USB MIDI or audio interface?
Can you try to install these previous version to check if your problem is still there?

- pre-version 1.4(1): https://dl.dropboxusercontent.com/u/215 ... %29%5D.dmg
- version 1.3(3): https://dl.dropboxusercontent.com/u/215 ... %29%5D.dmg
Thanks,
