I am trying to help a friend over the phone with thier msn messenger they are trying to install on their computer. It is version msn messenger 4.0.1, and when they install it, and try to run it, it comes up saying, 'mounting the disk to image.' A few seconds later it comes up saying 'the mount did not complete (50). This is all I know about the problem, and as i search around the internet, i can't find a solution. A long time ago, they say they had msn messenger on their computer, and it worked fine, any suggestions?
