Hmmm, I don't know for sure, but it might have to do with the way your account is set up.
Click on "My Account" on the left
then on "Charting profile/options" under "other settings"
and scroll all the way to the bottom
Are you using "Advanced" as your default detector? If not, change it to that and see if that helps. If it's not that, I'm not sure.
If you "friend" me, I think I can view your chart. Although, I am by no means the chart guru, I might be able to help. (carly375 or *carly* is what I am listed under, not sure how can you search for me though carly 375 is my signin, but *carly* is how it shows up when I post)
