NO LONGER COMPATABLE!?! – GarageBand Review

I own a flawless 1st. Gen. iPad. I was forced do a "factory-restore" and then I did the recommended OS Update to get the locked device to work again. Imagine my surprise as I discovered all the "incompatables" I received when attempting to reinstall my favorite paid-for apps. I am distressed to find that GarageBand no longer can be downloaded nor does it function. What is the deal with that? Is there a fix? If not why?
