Can you add \\tracingmacros1\ after the \\makeatother\ and attach the resulting TeX log file? Maybe it'll be obvious from the expansions what's getting in the way? (sorry - my MiKTeX installation is lazily out-of-date, and I haven't got an easy-to-hand VirtualBox at the moment to put a latest-and-greatest one with PMX on!)
