You want to use the beta SMP version--it will eventually expire and need an update, but it folds FAST! And it is the native version needed for Intel Macs.
Remove ALL traces of previous folding (search for f@h and fah and folding, I suppose) then gat "SMP Client Installer" here:

You won't need the terminal--it's a nice pref pane now. But at least during the beta period, be sure that:
a) You run it nearly full-time (deadlines are vey tight)
and b) You don't change your network (like pulling the Ethernet out or even losing yoru WiFi signal accidentally) without Stopping folding first. (This is done via System Preferences now.) My Wi-Fi drops out a few times a day, and all work is lost when it happens
But Stanford knows about the issue I think.
InCrease may be useful, but I believe it's quirky with SMP still.
If you're already using SMP, then maybe it's just a temporary outage at Stanford.
