uploading files

I'm trying to upload for the 1st time. It's a SolidWorks 2009 file. I get an email with this message:\\

We were unable to add model Iphone Holder to 3DContentCentral. Details follow.

SolidWorks error: #Dependency file(iphone 3G.SLDPRT) missing for model(Iphone  Holder.SLDPRT).

Please advise,

Thanks,

MTM
