Unable to purchase logic pro x?

Question

I keep attempting to buy Logic Pro X on my Mac App Store and it will not let me.
It keeps giving me the error: "We cannot complete your request. There was an error in the Mac App Store."
I am able to download other applications. My Macbook Pro is brand new, 15', Retina Display. I have more than enough money on my credit card. I have tried resubmitting my payment info, changing my Apple ID and password, signing in and out, rebooting, and a million combinations of all those. This is the third day this has been going on and it is infuriating. I paid ample amounts of cash for this computer and all the features that come with it, and a glitch like this occurs? What gives, Apple?

I think you have become very confused about 64/32bit stuff..
Simply put; (well as simply as is possible... in layman's terms  )
OS X Lion or Mountain Lion runs in 64bit on 64bit hardware architecture.  Modern Macs all have 64bit architecture
Logic Pro 9 could run in both 32bit or 64bit mode in Lion or Mountain Lion. The benefit of running Logic Pro in 64bit mode was it could access the Mac's memory above the 4GB 32bit addressing limit. Running any app (including Logic Pro 9) in 32bit mode... limited it's use of memory to 4GB as a maximum... so if you had 16GB of RAM installed most of it was never used by a 32bit app.
Again the fact your OS X is running in 64bit is neither here nor there in regards to the apps themseves.. as both 32bit and 64bit apps could run in a 64bit OS. However older 32bit OS's could not run 64bit applications.
Logic Pro X only runs in 64bit mode... and requires a 64bit OS such as Mountain Lion.
Hope this helps...
