Uploading file using api but couldn't see the file in box.com

Hi,

I am trying to upload file (using BoxCCGAPIConnection) and it gets success. When i try to re-upload the same file i get the file exists error which means file is present in box.com. However, I cannot see it when i log in to box.com. 

I have the admin access and see content section and even that is empty and i cannot see any files. Could anyone let me know what I am missing here ? 

Thanks.
