Glad to hear it, Sun! I don't think anybody thought to mention, you need to do a re-start, at least of folding, so that it takes effect with the next WU. From a mod over at the forums:
"And yes, the folding core needs to be restarted to change the settings it uses. Otherwise they will be used by the next WU. However, making changes in the middle of a WU can sometimes cause it to fail. This is less common than it was, but does still happen."
