Please help...

I have not had issues with flash fall year.  Now as of a week ago it is not working.  I have an online course.  I have switched all speaking assignments to a new plug in which uses flash.  I wanted to NOT use java.  However, now none of my listenings will work and the speakings are not functioning either.  All IT departments have cleared cache and updated flash.  I know it is some security issue as the listenings will work in Explorer but not other browsers.  The speaking tells them, please check flash and browser restrictions.  Please help.  I had no issues and now it is a nightmare.
