sigh, that is covered elswhere, and the .dll isnt the problem... what is happening, is that continuum is continually opening and shutting down, that's why it bounces in task manager. Then, you decide to shutdown (while continuum continues to open and close) and eventually the system WILL be attempting to shutdown when continuum is trying to open. So windows whines that the .dll !@#$%^&*ociated with continuum won't run because windows is shutting down. General forum hint: beware information from 'unregistered' users. 100% of the time, it has been some "anti" spyware or "anti" virus app that doesn't like continuum, or vice versa. Disable/uninstall/allow continuum in each of those types of programs that you run. Eventually it will run, when you figure out which app is the offender.
