Hi everyone,
I am new in this forum.... Does anyone can tell me :
1) if the window live suite is a free download?
2) I tried to use window messenger but everytime I wanted to go further it always told me that I needed to install the window live suite, then gave me a code: mentioning"catastrophique failure.....

Now, i am desperate and really need your help. Thanks a lot.
Laurencer.
