im guessing WLM and IE use the same cache? it they dont they u will prob have to go into C:\Documents and Settings\%username%\Application Data\Microsoft and go into the windows live folder and delete one of the folders in there but i dont suggest this approach unless u know what your doing since i dont haev WLM installed but this location is where the MSN messenger v7.5 saves its info
