Azpen 728 and McAfee Mobile - Oh please help!

[VoE]

Tiger Direct offered a bundle of the Azpen 728 and McAfee Multi Access that after rebate would be $10. Myself and 2 other co-workers each bought one. We downloaded McAfee on the first tablet, and it was fine. When we tried to download on the 2nd with a different key code, it said that this was already linked to the 1st...then on the 1st tablet, the McAfee was not active anymore. We finally figured out that the chip is an A23, and it has an imei number...all three have the same imei number. The tablets are wireless only, not 3 or 4g. Anyone else have this problem with McAfee? I tried to explain this to McAfee, and they are lost.
