Hi modyzinc, and welcome to AF
Firstly, apologies but I've merged your threads. As you posted first in All Things Root I assume that the device is rooted, but may have that wrong.
Also apologies because there is a limit to what I can do to help as I don't know this device - hopefully someone else who does will be able to do better.
My best guess is that you might have a version of the play app that doesn't work well with your ROM. If you tell us where you got it from/what version that might help. You could try clearing data for the Market app and then see if it's any better, but that's a bit of a long shot.
It seems odd that a stock
ROM didn't include it though. Maybe it will help someone if you can say exactly what file you used there too?
