I am having the same problem. I can add projects and everything fine, the colors are saved, etc. Unfortunately, the bars do not show up on the main page and the "Sample Colors" column shows no colors (just white boxes).
I detailed my findings here: http://www.s9y.org/forums/viewtopic.php?p=11480#11480
I just found this, so I'll keep up here I guess!
