well, I'm new into BAM and Boinc

Installed it as the instruction from faq showed

and now there's the problem that when i sign up in boinc to use BAM, and try to synchronize them, the BAM userID is other than the one on main page, and the host ID is also other...

so i cant get the host to work ;/

any ideas how this can be solved?

This happened to me too when I first tried to join, although I was not new to BOINC when I did, just new to BAM. There may be easier solutions to your problem and someone else may post a reply soon. What I ended up doing to solve the problem was to delete my account here and just start all over again. If you do, make sure you use the same e-mail address to create your account here as what you used if you are already attached to any projects in BOINC and also make sure when you attach to BAM to also use the same e-mail address. Good luck!

did as you said,
and nothing worked ;P
still the same (old and not equal to the new ones) user id and host id diplayed in boinc when tring to synchronize ;/
