Ok.. Google tells me that this 'Undelete Plus' program has nothing to do with Messenger Plus! Live, thank god.

Simple answer: You can't.

If you deleted them and you're trying to recover them with a dodgy program, that's the best you're gonna get.

Try a different dodgy program if you like.

Messenger also keeps a 'message history', you might want to check that too.
