If usinng the CLI version, run

From
MDE's SETUP GUIDE
What the flags do (courtesy of GLeeM with an addition or two from me):
-local = makes the client use info from directory it is in rather than the registry. If you have never installed the GUI you don't need to use this. If you have installed the GUI you DO NEED to use this. Also, use this flag if you're running two or more copies of the CLI version.
-verbosity # = writes more info to the log making it easier to troubleshoot, the higher the number the more verbose the log. Highest number is 9.
-forceasm = if the client or computer crash, the client thinks it is it's fault and when restarted does not use optimized code which takes like ten times longer to finish WU. This flag prevents the client from checking prior termination so that it will always use optimized fast code.
-advmethods = says that you accept the risks of doing late beta WUs, You need to use this flag to get the double point BigWUs.
-oneunit = after sending in results the client quits without getting a new WU. Useful for doing the last WU before quitting F@H. And useful for making your own queue.
-queueinfo = for the console, shows in the log if you have any unsent WUs
-send all = sends all finished WUs and then quits. Useful if something happens to the
F@H server or your connection.
-config = configure the console and continue work
-configonly = configure the console and quit
