I’m frustrated

No Signal or sound when using Oxygen 25 with Logic Pro X on Mac OSx Yosemite.

Received my Oxygen 25 through the mail today. At first, the sound worked fine. After installing the included synths and attempting the directlink drivers, however, both the signal and sound were lost. The faders/Knobs work in "AUTO" mode but the keys are not recognized. I attempted to play the software instruments through the Oxy's keyboard and hear/receive no signal. I deleted the drivers, uninstalled the synths, trashed my Logic Preferences and even reinstalled Logic. The problem still persists. Any suggestions?

P.S. -I'll only hear instrument sounds when first opening up the program or when the save screen prompt is open.

Also, the MIDI WIndow in the Audio MIDI Setup shows that the device is recognized (even when I test the setup).
