I found the solutionat http://blogs.adobe.com/flexdoc/2010/03/using_the_adobe_community_help.html.
Apparently there was an issue with the file locations on Windows 7 64 bit.
All you need to do to fix is copy the missing .helpcfg files from your preferred language directory in
C:\Program Files(x86)\Common Files\Adobe\HelpCfg
into the corresponding folder in
C:\Program Files\Common Files\Adobe\HelpCfg
Then restart help. Thanks Tim!
