When addding second users, BB stops syncing..

[helpdeskBelga]

Dear,
when adding a 2nd user to the bes server the sync stops for the user that is already configured. The new user can't activate his device.

I can see that the idm and zdb files are created for the new user.

In the bes MAGT log file, I can't see any error.

the registration mail of the BB service we can see in the user's mailbox to, so this is going fine..but the device doesn't activate and the other device doesn't sync anymore
can you please help me? I'm stuck on this one
thanks!
