Unable to edit Metadata of psd file in Bridge..

Hello,

     I'm trying to Edit the Metadata for a Photoshop file in Bridge.

     When I click on any of the IPTC fields (e.g. Creator) I get an Error message saying that the Property cannot be modified. (Please see attached image).

     The psd file isn't locked. It appears in Bridge as "I Want You, Baby.psd" - also shown in the attachment.

     Any idea how to fix this?

     Thanks in advance for your help.

Regards,

Rajnesh
