FwPopupSink: cfp.exe application error

An exception violation has occurrend at . The memory could not be ‘read’. Second time I’ve had this error. It happens only at startup. The cfp tray icon continues working. If I try to bring up the UI it displays it partially and freezes. Again the tray icon STILL continues to work displaying traffic and responding to rightclick commands. Upon clicking OK cfp.exe terminates and the tray icon disappears.
