suggestions on to get back xp after installing vista

since upgrading to vista beta 2 i have had a lot of problems running everything, when i start my comp i get a dual boot screen for windows vista and an earlier version, if i select the earlier version of windows it goes to a black screen and thats about it. On top of this i run a couple of cad programs which now either won't run at all or crash after opening. can anyone suggest anything to help or tell me how to get back to xp as i need to get on with my work :)
vista does look cool thou

After upgrading to Windows Vista, you can't go back to XP, you have to format the drive its installed on and reintall XP, so make sure you back up your data. http://windowsconnected.com/blogs/andre/archive/2006/06/08/3002.aspx -- -- Andre Windows Connected | http://www.windowsconnected.com Extended64 | http://www.extended64.com Blog | http://www.extended64.com/blogs/andre http://spaces.msn.com/members/adacosta
