Since the update I can't see any host, no projects, nothing, can't find out what I need to do to display anything, I used the old system for over a year, my credit still goes up as shown on my projects home page, but Boinc shows nothing at all

Check the answer here, it applies to you as well.

You have no hosts attached to BAM! and no projects in your account.

Thanks for the prompt reply, however this still does not help, I've followed the link, but there is nothing to give any clue whatsoever as to how I add my hosts/project.
I followed the links and instructions as far as I could, however the options you gave were not available.

bring back the old site, at least it worked out of the box

This has nothing to do with the old site. You created an account two days ago. Apparently you never used BAM! before. So how do you expect to find things that aren't there?

I think you are mixing up BAM! account and stats entry.

If you have no clue what BAM! really is, then click on the BAM! logo in the top right corner and read the page. Read it, don't glance over it.

If you are simply looking for your host STATS then search for your name (under which you created project accounts) in the top left corner, find the correct result, click on the charts icon and then click on the "Link to users host stats" icon.
