I am having the EXACT problem as the person who asked this question last month. I copied his question with a few changes and one additional problem:
"Am using Access 2002, with a database I set up several years ago. It has worked perfectly until today, when I suddenly got the error message "Your Microsoft Access database contains a missing or broken reference to the file 'plugin.ocx' version 1.0" "
I did what you guys suggested. There were no missing files in the References section, and I did not find the file plugin.ocx on my machine. I have not applied any patches to my Access application. Should I request that patches be applied? Which ones?
