Two days ago I began to be unable to get into MSN on my computer. It is a Compaq Presario 6000 running Windows XP, with Norton Anti-Virus. At this moment there is no anti-virus on the computer, as the Norton became corrupted, and I had to uninstall it, and now the computer will not allow me to re-install it. Today I downloaded the free version of Registry Mechanic, and it found a number of problems, however, when I went to purchase it, the computer will not allow me to go to the site, because it is secure. Last night I was reading in another thread here, and read the solution of going to "Start - Run - /type something something...sorry, it has been a very long night...anyway, when I tried to do that, it came up and told me that Windows could not find those items. This has become very frustrating, and as there are four of us using this computer, for work and school, I would appreciate help as soon as possible.
