XP Computer Died. New Windows 7 Computer, Upgrade Ghost from 14 to 15?

I have Ghost 14 that was on my XP Home computer and, since it decided to give me a New Year’s Day present by expiring, has been pretty much replaced (I have hopes of still raising the dead :)) by a Windows 7 computer (CyberPC gaming computer if it may make a difference). I want to get Ghost back but hear that 14 is not quite fully compatible with Windows 7. Although getting 15 would not be financial hardship, I would prefer to remain with 14 (I don’t want to buy something if I can get along with what I have) if it can be expected to run on Win 7 about as well as it did on XP. I would appreciate advice and/or assurance either way. Thanks, Russell
