I upgraded from 2007 to 2008 sp1.1 recently. I have over the years created a custom sldmat file for materials that my company uses. If I open an existing 2007 part that uses our custom material everything is fine. If I try to edit the material in 2008 and use our custom materials data base I now get: "Incompatible Material Database. Probably this database may be of Higher version and not compatible with present version. 0xc00ce201 : Error parsing '0' as hexBinary datatype. The attribute 'RGB" with value '0' failed to parse." Does anyone have any suggestions?
