Windows 7: Windows Live Movie Maker 2011 Compatability

Back in July I was able to run Windows Live Movie Maker 2011 without problem. However, now I get the error message "Movie Maker can't start". It appears that the graphics driver, although the latest from HP, is not the latest from Intel, which Movie Maker now requires. I guess that in August there was a Windows update that updated Movie Maker 2011 to require this. Is there a way to get the earlier version of Movie Maker 2011? I can't get a sensible response from HP as to when they will update their driver.
