Replying to Vegas keygen help.

So i tried to open vegas today, and it would not open, the little timer came up, but it wouldn't open, even after restarting. i looked up that the only thing to do is to re install it, so i did and when i went to do the crack and keygen, when i copied it into the serial number box, it shows up as invalid.
i have tried lots of them but theyre all the digital insanity keygens and none work. and i was just finishing up a project that i spent countless hours working on, but never rendered and now its gone, until i get vegas pro 11 back. and i dont feel like changing softwares now and re doing everything, id honestly rather forget about the edit then do that.

could someone help me get vegas pro 11 back? pleasee!
