I have uploaded mempatch.sty to UK incoming. Please use this to replace 

the current macros/latex/contrib/memoir/mempatch.sty.

mempatch v4.0a fixes a problem with the starred section commands in the memoir class. I will shortly be issuing a further mempatch with added functions, so if you don't use section*, etc, you could wait for the next patch.

i've installed the package; thanks for the upload.
