Use the System Restore and restore the PC to a date PRIOR to installing the updates.  Assuming the updates are the problem that should fix it.   System Restore can be accessed from Start/Programs/Accessories/System Tools. 
I was using Cyberlink Director 8  ~5pm yesterday.  Downloaded  a suggested update for latest dell support software  ~8pm.   Went to continue my project today and both Dell support software and Cyberlink continue to get "failure" messages in windows to "close program" and search for solution.  I've attempted to removed dell support software and reinstall POwerdirect twice.  still getting fatal error :(   thoughts?
