Problem With New Themes - MEMBERS, GROUPS and BLOGS pages stuck on DEFAULT theme

Hi, Everybody,

Can anybody help me with this issue? I installed Buddypress using SimpleScripts on my Bluehost, and everything seems to be working fine. Until I upload a new theme to my site, and notice that the MEMBERS, GROUPS and BLOGS pages seem stuck on the old theme. I tried everything I can think of, including going to my FTP folders and making sure bp-themes was set to 755, as Andy told me. But that does not work! I have noe spent hours trying to fix this and have installed Buddypress SEVERAL times over and over again. Nothing works!

I also tried installing all themes from here, both automatically and manually, using my ftp program. Same results. So frustrating...

Ideas please?!
