I have (or rather, had) NIS 2010 on my system, however 2 days ago, my computer started acting weird, shutting down etc, after trying to get it restarted numerous times, eventually it came on but then i was automatically directed to NIS 2011, saying it was downloading onto my computer & that the NIS 2010 was being uninstalled. It took hours, literally because half way through downloading & installing the newer version, it just kept shutting down. eventually it came on & was ok for a day. then i manually shut it down, but now it just wont come on at all, theres nothing, not even power, even though my power cable works fine. I was a little suspicious when all this installing & uninstalling was going on, as at one point i had a load of foreign writing pop up on my screen. is it normal for the 'upgrade' from 2010 to 2011 products to just automatically 'happen'??
