Hi.

My old account is here : https://boincstats.com/en/stats/-1/user/detail/34102.
And when i have joined new projects with BAM, i have created 19 new account, no syncing: https://boincstats.com/en/stats/-1/user/list/0/0/183362228/0

I used BAM with the same email, the same password, so... i don't understand.
All computers work with all projects...
All members of my team have the same problem. ^^"

Is there a solution?
Delete some accounts and recreate them?

I listen all ideas.

Any luck JDZ? Get things fixed?

No chance: no change! ^^"

I see your multiple stats entries here and it looks like all but the "primary" one you listed have just one project of stats. This looks odd so I want to confirm a few things from your post.

When you join new projects from BAM you are logged into BAM with the primary account and going to "Sign-up for projects"?

It does not look like it but does your username, email address or team name have any non-basic asci characters in them (e.g. a grave)?

Well,

yes, i have "sign-up for projects" with the same BAM account.
My username is JDragonB, my email contain letters (unaccented), dots and @, my team is TWINOIC... so i don't see any non-basic characters.

All members of my team have the same problème.

You have passed step 1 - same email on all projects and none of the projects should be messing up your email because of bad handling of special characters.

Step 2 - you said you have at least one host that is connected to all projects, so this should allow all the project user CPIDs to sync up.
SETI@Home appears to be your oldest project so its CPID (84aa788271c320ce2785e43e8924111a) should be your default. You currently have SETI and WCG on this CPID.
On a host with all the projects attached, in the BOINC Manager go to the projects tab/screen, select SETI and push the update button. Give it a minute or so to sync (you can watch the results in the event log).
Now pick one of your projects that is out of sync, go to the project website, login and go to your account page. Look at the listed CPID and it should be different than your SETI CPID.
Now go back to BOINC Manager, select that project and push the update button. Give it a minute or so to sync. Then go back to the project website and go to your account page. Look at the listed CPID and see if it has updated to match your SETI CPID.

I have tried with SETI/UNIVERSE, with SETI/YOYO, with SETI/GPUGRID ; before a BAM syncing, after a BAM syncing... no change.

Not a BAM sync, a project update.

Not only a BAM sync : 2 projects update, a BAM sync, 2 projects update...

Magic ! I have 11 projects on my user signature graphic ! I hope that old stats will be deleted on my team, next day ?

Good to hear.
You were trying to do all the right things but for some reason the BOINC client and project servers were not cooperating to sync your CPID.
