I feel stupid for asking because Ive used SW for along time and have seen this message before but after doing so research on the Internet and my SW Bible I have yet to get the answer Im looking for. I opened an assembly that has an assembly in it and I had errors that told me to edit definition in the assembly that is referenced in this assembly. I opened that assembly and there are no errors. I checked all the parts and there are no error's. So could some please define exactly what I need to look for when i see this error. Thanks
