Current Playback Engine does not Support a Sample Rate of 48 Hz

[yasita]

I know this issue has been fixed a thousand times in these threads but none of the solutions I've been finding has worked for me.

Brand new Pro Tools download, all brand new hardware equipment. All necessary drivers should be installed and currently up to date.

I'm trying to open a file from an online tutorial. When I try, I get this error and the file won't open.
"Current Playback Engine does not Support a Sample Rate of 48 kHz"

Specs:
I am using Windows 7 64-bit.
M-Audio M-Track 2x2M C-Series.
Version 12.8 of Pro Tools.
i7-2600 CPU @ 3.40GHz
(RAM) 16.0GB

I have tried changing my default device in Windows Sound to something that is not my M-Audio M-Track 2X2M.
In the Windows Sound Window my "M-Audio M-Track 2X2M" is under "Speakers" and is currently set to "Ready" not "Default Device".
(When I do this, I can not hear audio from any program INCLUDING pro tools.)
I have tried closing all other programs.
I have tried restarting pro tools.
In ProTools->Setup->Playback engine my Playback Engine is set to M-Track 2X2M.
I've tried restarting my computer.
I have tried holding down the 'n' key on pro tools start up.

I'm new to this, is there anything else I can try?
