I WAS ABLE TO FIND THE SOLUTION MYSELF...
HERE IS ALL YOU WILL NEED, TO FIX ASSOCIATION PROBLEMS:
From a command prompt;
assoc .bat
should return with
..bat=batfile
If not
assoc .bat=batfile
to restore the default file type association.
ftype batfile
should return with
batfile="%1" %*
If not
ftype batfile="%1" %*
to restore the default "Open" action for the file type.
