We recently upgraded to movie maker 2012 on a dell laptop running windows 7.  Movie maker 2011 had worked fine but 2012 will not run any video clip form any disc location.  It appears to have crashed before and opens each time with a message saying it can recover the last project.  No matter whether we say yes or no, the program does not work.  After this happens I find that movie maker.exe is using high proportions of CPU capability - 25% or multiples of 25%.

Any ideas how I can make this run as the old version was good and we wanted the improved functionality that 2012 was supposed to give.  I will go back if I have to to the earlier version.

thanks for any help
