Visibility problem Catia Product File

[TheMan51]

I am having a problem with my catproduct file. When I look into my assembly a part is not showing. The part number is in the tree but the part is not visible. I am getting the error " The files in the following list could not be found or contain the wrong information for the active document"
It is looking for "DOC50". This catpart no longer exists.
Am unable to insert this part into an assembly. Any help would be appreciated.

Go to File --> Desk
Right click over DOC50 - Find
A browser window should open, go find the document.

If that does not work

Tools --> Utility
CATDUAV5
