I have installed Zen Cart on my website but cannot seem to upload anything.

The installation was done earlier this week (version 1.3.9h) and is hosted by BlueHost. I am usinf Filezilla for my FTP.

I have tried uploading:
1) It's Christmas template, and;
2) A new logo designed in Photoshop

Filezilla says that the files have been successfully uploaded to the server so what could possibly be the problem? I am totally baffled.

BTW I am using WIndows.
