You have more points than me, so you probably know what you are doing with this stuff already. I take it the program is connecting and folding, you just aren't finishing the work for points? Not sure what would be causing that.
If you grabbed the 'high performance beta client' 6.23 for MPICH and installed it, be sure to grab the 6.24 'drop in binary' and toss that file into your install directory, replacing the original. The guide on the F@H site has some steps to run through, if you haven't tried it already. Rename the client to something simple like fah1. Create a shortcut to it, open up properties on the shortcut, add -configonly to the target. Run the shortcut, input all your settings you want. Once it runs through options and closes, open the shortcut properties again, replace -configonly with -smp and start folding.
