I woke up turned on my MSN and all custom emotions were gone
What happened I dont even remember where I got them all.

I bet it was posted already but I did search and didnt find anythin' so sorry

So when you go to "My Emoticons" there are none there, just the default ones? And do the default emoticons work?

happens to me sometimes, theres reallly no solution, for some reason they just get deleted when i install a new version or maybe if messenger crashes, but if there gone the place they would be is in your application data, or gone, and you will have to just slowly regain them like i seem to have to every so often

It's probably the map.dat file with the CEs getting corrupted. The only solution is to re-add the CEs.
