Disppearing Emoticons

[asfz77]

I had a number of custom emoticons that were working perfectly well on one of
my messenger accounts.....until I was stupid enough to think that I could
copy them to another account from behind the scenes. I tried to copy and
paste these emoticons from one MSN Messenger/customemoticons folder to
another. Now they won't work on either of my messenger logins. Does anybody
know how I can recover these? I still have all of the emoticon files and the
original map.dat file but nothing is visible on the messenger emoticon menu.
TIA.
