Yesterday, I received email in my Outlook Express, I then hit the start button to switch users. All was normal till I clicked on receive mail in the other user account. This message came up-" C:\programm files\outlook express\ msimn.exe  This application has failed to start because the application configuration is incorrect."  About the same time Trend Micro popped up with a box stating it couldn't quarintine the problem it found. I then shut down the computer. Now I have numerous problems. In addition to Outlook now starting, neither will my Windows security center, Trend Micro and so on. The desktop has a gray box overlaid on the taskbar. If I hit the start button key on the keyboard, all the documents and program lists are blank. Desktop properties will not let me change settings. Also the XP welcome screen has dissapeared in favor of a login box only. Internet does work, but the browser has most menus hidden at the top. Has anyone seen this type of faliure or know how to fix it?

 

Many thanks in advance
