iirc grits you have run the latest already so you are fine; Donz said he used an older one, how older I do not know.
As far as your question about sfc /scannow with WM, if you used the newer files then there are No Problems using it anymore since previously a necessary registry entry was added to the WinMailEdit.reg which circumvents that particular System File Checker problem of the past where where SFC would restore the original msoe...dll causing WM to fail, but not anymore; if it does then you don't have the latest files.
