My wife purchased ms flight simulator X gold afew years ago,and i've installed it to my pc several times as hard drive went out , blue screen zapped memory , any way microsoft now tells me that i've installed it too many times and i can no longer register prod code . is there a way to re- register without re- purchasing game ...i thought that for $ 60.00 i should be able to play at any time. and no this has not been loaded on any other computer as the microsoft activation ctr has claimed
