I've been playing with BAM for some weeks now but absolutely cannot get the CPID that BAM thinks I have to coincide with that shown by BoincManager (and consequently with that shown by BoicView which I use across my home network). That in BoincManager is consistent across all projects and duplicates successfully when I attach new projects. It is also the value shown in client_state.xml. As a result the "My detailed stats" link claims no credits, though the original Boincstats shows credit growing steadily (check out user annieb).
I've reset all projects, attached and detached all projects, ensured all machines are simultaneously attached to all projects, tried to reset the cpid in BAM and all to no avail. I've also (where possible, see below) merged all duplicate host computers.
Two things that may be confusing the issue. Firstly I run HashClash which is not BAM compatible. Could it be that it somehow prevents BAM from catching the right CPID? I've tried detaching and leaving for a week or so, but of course I'm still a member. Secondly I run XtremLab. This has had a problem for weeks now with automatic creation of duplicate hosts. AND they've turned off the merge computer feature so I can't fix it. Again could this confuse BAM?

Anyway I've decided to quit BAM for a while. It seems to be another layer of complication offering little over BoincView. Willy's doing a great job here, and I'm not complaining, I just want a simple life.

A shame you quit so quickly while all is wrong is your BAM CPID not lining up with your BOINC CPID.

The cause of this was a simple programming error in the changes needed to support WCG.

if you take the trouble to check out your BAM! account once more, you can see the link to your detailed stats now works.

I didn't exactly quit "so quickly"; I'd been playing around for some weeks.

But anyway, many thanks Willy for fixing the issue for me; I appreciate it. I will reconnect my hosts, though it may take a while as one of my machines is in the middle of a game my son's running, so I can't get to it right now.

Thanks again.
