I've had my account for months now, and my CPID has not synced. I have at least 6 hosts that show up and have associated with my BAM account, but my CPID hasn't synced, and "Detailed Stats" shows "User ID doesn't exist in BOINC combined or doesn't have any credit."

Again, this has been months, so I don't think it's going to automatically fix itself.

Thanks,
Sam

The fact that your account shows zero credit suggests that something isn't set up correctly... Are you using the same user info (name, email, password) that you do at the projects?

Aside from one project that has particular password requirements, yes.

Hi BigSam.
Did you grant access to your statistics on your projects' preferences if necessary?
There are some that won't let Boincstats (or other statistics sites) access them unless you allow them to.
If you happen to only let your machines work on those projects Boincstats can't have anything about your contribution.

Yes, I did. Interestingly, on most of the project sites, I can see stats from the other projects. On this site, I can see some of my computers. But still no consolidated stats/CPID.

Have you attached BAM! to one of your hosts?
