You must attach your clients via BAM! to projects and not the old way, via the BOINC Manager. In order to do that go to your
host lists page and select the host to which you want to attach a project. Then click to open a new page, from which you can choose to which projects you want this host to be attached to, After you made your choice press "Set". Then go to the BOINC Manager on that host and click on "Tools -> Synchronize with BOINCstats/BAM!" and your host will be attached to the projects you have chosen.
Also if you have more than one host and you want all of them to be attached to the same projects then go to your
resource page, put a tick on the "Attach all hosts now" for the corresponding projects and press "Update". They you have to go to the BOINC Manager of each host and again click on "Tools -> Synchronize with BOINCstats/BAM!".
BTW, next time put a more meaningful thread title
