Cannot select vendor when creating new DC

Hi all,

I'm using NWDI, version is 7.14.

When I try to create a new DC the vendor dropdown is disabled and all I see is sap.com (see snapshot - http://img390.imageshack.us/my.php?image=newprojectjq3.jpg).

I have opened several projects in the past with no problem (and I could choose my own vendor, the one I created in the SLD).

How can I solve this?

Thanks,

Omri
