I have been working on this CPID problem since Nov 2006. There isn't an easy to fix it. The only thing that helped was on the 23rd of July I detached (Delayed Detach through BAM) 15 of 16 PCs from all the projects which left one connecting to project servers. Within one day the CPIDs were sync'd. Then, once my average total credits went from ~300K to ~400K, to 1.1M I started attaching one at a time after renaming them since the projects have that PCs name/CPID. Since, it was would have taken too long to rename and get them back up and running, I stopped at 2.

So, My bad, After all were attached the only CPID probelm was with the down projects. But now the old CPIDs are coming back.

None of the so called thing to correct or keep them sync'd is true. I have been using the same username, email, country, URL, zipcode, and password since I started running BOINC Projects. I have had all PCs attached to all projects all the time, except for this last mulyiple detach in July.

CPIDs are really stupid for users since they don't work. Email addresses work and user IDs work. Every project I attach to asks for Email and password Not CPIDs. What can't BOINC Get this straight?

Good thing they don't use CPIDs for teams, at least their scored are correct.
