Hey Duke, did you use a different email account when you added BU to your list of projects? That is what usually causes split CPIDs. Make sure all your projects use the same email account. And like Maxwell suggested, on one machine, you must crunch several wu's from most/all of the projects you have created accounts for. So of course it could take days/weeks to go through all your projects and then you'll have to wait awhile longer for BOINC to sort things out.
