Thanks for the reply. I apologize for not reading further down through your answer.
I attempted your second solution by doing as SAVEAS to a local folder and copying the 'new' file back into the original directory over the previous. When I launch the file from the project manager tab, it does not give a prompt to use the project's default setting. When using AECOMPONENT, it gives me the same exception.
I attempted your first solution by renaming the project to "Test.wdp" and opening it under the project manager tab. After opening the non-reference drawing and using command AECOMPONENT, I again get the same exception. This error is only one this one particular project; I haven't seen it anywhere else.

Ron
EDIT:
Scott,
After looking more closely at the .wdp file for the project, I noticed that the file pointer for the wd_menu.dat and component library somehow changed to what is probably a default position for Autocad. After changing them to the correct directory, the exception no longer occurs. I would say this problem is solved but I do not know how this directory changed as I always copy a previous .wdp file to use on new projects before I load them. If it occurs again, I will update this thread. Thanks for the help!
Regards,
Ron
