Visual Studio Intellisense not working ( ctrl+space)

My Visual Studio Intellisense was not working. When I was in the Immediate window I was sick and tired of not being able to ctrl + space to get my intellisense. I have Microsoft Messenger Plus! Live installed and apparently they have a preference that overrides the ctrl + space. Here is how you fix it. 

1. Select Plus!
2. Preferences and Options...
3. Click on the "Messenger" tab
4. Select "Messenger Lock"
5. Uncheck "Activate Messenger Lock with a system-wide shortcut: or change the hotkey bind.
