Ok, don't panic.
You will have to enable your system to veiw hidden file extensions.
Do this by opening My Documents, go to "Tools",
click on "Tools" in the control header and then
left-click on "Folder Options...", a Folder Options control panel
will open. In that panel click the "View" tab and go down to
"Advanced Settings" and double click on the folder marked
Files and Folders to open it. Scroll down to the checkbox
that says "Hide extensions for known file types", if the box is
checked then go ahead and uncheck it, then click "Apply" and "OK"
to close the Control Panel. You should now be able to see the
file extensions listed along with the file name. Then go back and
follow the illustrated instructions above. [
