Solution!

remember i said that i couldn't open my live messenger? i've finally found a solution! here are the steps:

1. go to C:\Programme Files

2. select the file named MSN Messenger
3. find an application named msnmsgr

4. right click it and select "Properties"
5. go to "Compatibility"

6. click at the box "Compatibility mode".

7. select mode as "Windows 2000".

Then they will ask you to install some stuff or so on, just follow the instructions. (i cant really remember this part)

8. finally, restart your pc and you should be able to use your live messenger now! :)
