I have recently loaded Norton Internet Security 2009 as a free update from 2008. Since the new version Windows Live mesenger is very slow in loading & often does not load at all. There is no error meesage. I have deleted the MSN cache folder which seemed to improve the situation but next time I tried MSN it took ages to load up. My daughter’s MSN loads eventually but my son’s with many more contacts does not load at all. Any thoughts?
