Well, you could try what MarkWP suggested. I can't for the life of me remember which free program I was thinking of since it is at work and I have the day off.
Also, since you are saying that the only thing you need XP for is for 1 program, have you considered just installing a Windows XP virtual machine in Windows 7 and running XP from inside Windows 7? This might not work, but it might be worth a shot. If it does all you would have to do is go into disk manager and delete your old XP partition and resize the Windows 7 partition to regain your disk space.
Windows XP Mode and Windows Virtual PC, available on Windows 7 Professional and Windows 7 Ultimate, allow you to run multiple Windows environments, such as Windows XP Mode, from your Windows 7 desktop.
