Open notepad, create a file with this:
yam.exe --config <your-config-file>.cfg
(your config file would be yam-mmc.cfg if you didn't rename it)
Save as a .bat file (Drop down Save as type All Files). You can name it whatever you'd like as long as it ends in .bat.
Make sure this bat file is in the same directory as yam.exe. Double click the bat and (hopefully) success.
That's what I do anyways, and it's always worked for me.
