Hello Gaspar, the link posted above with the screenshot is my store domain. The only thing I can think that might be causing this would be a possible caching issue. (Is all the caching, and indexing options enabled in the demo stores?)
Thanks for getting back to us on this. I would be willing to provide FTP access to the site temporarily, if you provide a log of your activities (as the store is live). Correspondence can be made via e-mail. (my e-mail information is available via my account info is that right?) My time zone is US EST (-5). Let me know when communications between myself and your support can best be made in this time format, and I will do my best to be available.
