since everyone is asking for it and wants it here I am posting it on this now
first you want to find out what type of computer you are running 32 or 64 bit most likely if you run xp you have 32 bit if you run 7 you most likely have 64
http://windows.microsoft.com/en-US/windows7/help/which-version-of-the-windows-operating-system-am-i-running
that page should help if you have vista or are running a version of 7 you are unsure of
http://www.vistarevisited.com/2008/07/19/what-version-of-windows-do-i-have/
those links should help plus if you don't know what version you are running you can always use google
if you want it dowload all these files first:
keygen
FOR 32 BIT Computers don't get if you have 64
FOR 64 BIT Computers don't get if you have 32
here are the instructions that came with my rar file:

but I will take screen shots of the most important parts of it
mmmk so the screen shots I am using aply to widows xp if you have 7 or vista you can help out by posting you're step by step instructions on how to do it but for now I am starting with win xp
first open the keygen after it has been installed
and select pro vegas pro 9 (32 and 64bit) series
then once you have done that the serial number should change you can hit generate or not it doesn't matter that much
then after this point hit patch
then hit local disk C
then programs files
then hit sony
then hit vegas pro 9
then hit ok it should start to patch the files 
DO NOT CLOSE THE KEYGEN OR HIT GENERATE IT WILL FUCK EVERYTHING SO DONT DO IT OR CLOSE IT ASS PIEafter you are done patching it run sony vegas again and keep the key gen open so it is going to first ask for the serial number
Then put in fake info and stuff cuz it doesn't matter and hit finish
If it has an error witch it does about 80% of the time don't freak out just hit cancel and the next step will pop up
Then enter the authentication code (aka the really really long one) 
And after that vegas should start up normally
But you are not fully done yet when you start up vegas for the first time it will ask you to update
DO NOT UP DATE I REPEAT DO NOT HIT UPDATE
and that is pretty much it
