I was trying to edit the material in a part using a custommaterials database. However, I can no longer access the databaseand I get a message that says:

Incompatible Material Database. Probably this database may be ofHigher Version and not compatible with present version.
0x00ce015: The attribute 'displayname' on the element'materialmodel' is not defined in the DTD/WSchema.

Does anyone know if this can be fixed? Also how do I go aboutadding other materials to the database?
