Fix this error / possible solutionThis error seems to indicate a problem with MSN Messenger's encryption routines.
The usual cause is that the time on your computer is not correct.
To correct the time on your computer, double-click the clock in the bottom right of your screen, in the window that appears you should check both the time and date.
If you use Windows XP, you can automatically correct the time by clicking the "Internet Time" tab, next click the "Update Now" button.
If you still have problems connecting with the time adjusted, try to run this file. This will make sure MSN Messenger can find all the files it need
