We have been experiencing some problems with users who sign up for the first time and don't see any stats. Usually this issue is quickly resolved as stats are gathered and the whole page is rendered. In those cases we have to force the download of the stats so that everything works correctly. You can usually do that by going to the profile page (in this case http://twittercounter.com/PercocoMarble).
I've now updated that page and the stats seem to have finally gathered and all other support requests can now be seen and responded to.
