Cannot install amazon apps

[James_frinzi]

Hi, I have tried to install the client for amazon kindle and amazon audible on my viewsonic viewpad 10. I keep getting an error about it not being able to parse or something of that nature.

Also, is there a way to install a different app market on this? I have. Moto Atrix, and it has an exceptional app market. This one is horrible in comparison.

Thanks!
