I purchased NFS back in Dec for 99 cents, I replaced my DX as it was lost, and I just recently got a new Droid. The Market is showing as purchased, but I am unable to redownload the game again.
I was able to redownload all other apps, both paid and free, this is the only app I cannot reinstall. When I try to reinstall it, and clicked the link (both the market via a PC and my Droid), I get a "This application is not available on your carrier" error, and my new Droid is showing but is is grayed out (in the Market via a browser on a PC, on the Market on the device, it simply wants me to repurchase at full price). Funny how if I chose the full price link, it is available for my carrier, wow, what a coincidence.
I found a forum on Google's site about this, and it is currently two pages long, so this is a issue people are aware of. I sent a support ticket to EA, and from what I am hearing, I don't expect any response.
It was only a dollar I am pissed I can't play a game I purchased, but it is a very small price to pay to know I should stay away from EA from now on.
