Symantec Ghost: "Not a Ghost Image File" whenever I try to open a .gho image file

Hi everyone-

 

A while back, I had my Acer laptop's hard drive replaced.  I took it to a small compuer repair shop, who installed a new version of Windows XP on the new hard drive using my serial no.

 

They installed an image.GHO file on my hard drive so I could revert to it whenever I need to reformat.

 

My problem: I can't open up the .GHO file.  I've used numerous version of Norton Ghost (12, 2003),Ghost Explorer, as well as Ghost Solution.  Nothing seems to be working, and I keep getting the same error message: "Not a Gost image file".

How do I open this .GHO file so I can "rewind" back to the old state?  I asked the computer shop how to open up the file, but they won't tell me.  They keep insisting that I go over there so they can charge me $50 to have it reformatted. 

 

Please help me out!
