WLC 5508 and LAP1310 - Not syncing up!

Question

As the title states I have a WLC 5508 and a LAP1310 that will not sync up.
The error stated in the traps log is "AP with MAC (xxxx.xxxx.xxxx.xxxx) is unknown."
WLC software release is : 7.2.103.0
IOS on the AP is : 12.4(18a)JA2
Upon some investigation I found that the "AP with MAC is unknown" error usually points to one of two things:
A.  WLC firmware needs to be updated
B.  AP needs to be updated.
C. The AP is not compatible with the WLC.
I am leaning toward solution C and I am looking for a conformation or a correction, if anyone could help out that would be greatly appreciated!
I've tried reading the compatibility matrix released by Cisco, but I found it mildly confusing as to what is and isn't supported by each software release.

Problem 11: 1250 LAP Not Able to Join WLC
The setup consists of a 2106 WLC that runs version 4.1.185.0. A Cisco 1250 AP is not able to join the controller.
The log on the WLC shows this:
Mon Jun 2 21:19:37 2008 AP with MAC f0:2x:cf:2x:1d:3x (APf02x.cf2x.1d3x) is unknown.
Mon Jun 2 21:19:37 2008 AP Associated. Base Radio MAC: f0:2x:cf:2x:1d:3x 
Mon Jun 2 21:19:26 2008 AP Disassociated. Base Radio MAC:f0:2x:cf:2x:1d:3x
Mon Jun 2 21:19:20 2008 AP with MAC f0:2x:cf:2x:1d:3x (APf02x.cf2x.1d3x) is unknown.
Mon Jun 2 21:19:20 2008 AP Associated. Base Radio MAC: f0:2x:cf:2x:1d:3x 
Mon Jun 2 21:19:09 2008 AP Disassociated. Base Radio MAC:f0:2x:cf:2x:1d:3x
Mon Jun 2 21:19:03 2008 AP with MAC f0:2x:cf:2x:1d:3x (APf02x.cf2x.1d3x) is unknown.
Solution: This is because the Cisco 1250 series LAP is not supported on version 4.1. The Cisco Aironet 1250 Series AP is supported from controller versions 4.2.61 and later. In order to fix this issue, upgrade the controller software to 4.2.61.0 or later.
Problem 16: 1000 series LAPs not able to join the Wireless LAN controller, WLC runs version 5.0
This is because WLC software release 5.0.148.0 or later is not compatible with Cisco Aironet 1000 series APs. If you have a Cisco 1000 series LAP in a network, which runs WLC versions 5.0.48.0, the 1000 series LAP does not join the controller and you see this trap message on the WLC.
"AP with MAC xx:xx:xx:xx:xx:xx is unkown"

What version of Premiere Elements are you using and on what computer operating system is it running?
What are the properties of this .mp4 video import (video and audio compressions, frame size, frame rate, interlaced or progressive, pixel aspect ratio)?
If you have any information about the video bitrate and audio bitrate of the file, that would be good to know.
What is the audio - stereo 2 channel or 5.1 channel?
What are you (manually) or the project automatically setting as the project preset to match the properties of your source video?
Let us start here and then decide what next.
Thank you.
