when I tried to create a new document based on a custom document content type. I received this error:


The document information panel was unable to load


The fix to ressolve this issue is to copy IPEDINTL.DLL


C:\Program Files\Microsoft Web Designer Tools\Office12\1033\IPEDINTL.DLL
to
C:\Program Files\Microsoft Office\Office12\1033\IPEDINTL.DLL


Afterwards word opened and displayed the panel and everything is working like a charm again :)


Good luck!
