So, I recently formated my HD so I had to reinstall everything again. I downloaded Windows Live Messenger 8.1 and before I could install it, it was asking me to send an SMS to some number to get a code I had to type in, in order to install, but the SMS is not free. I don't want to pay 2€ to have Live Messenger, I had it for free before.

Am I missing SOMETHING new? Do I really have to pay for it? 

Every website I enter that has something to do with Windows Live Messenger tells me it is free, but apparently it's not.

I hope someone clarifies me on this.

Thanks in advance.Messenger is still free and I've never had to send a SMS in order to unlock it.
Where did you download it from?
Are you SURE your computer is spyware free?
Could you provide us with a screenshot of the window that asks you to send an SMS?I got it from here www.msnmessenger.ms, also tried the 8.5 version from baixaki (it's a brazilian file hosting website) and it also asks me for a code.

Here's the screenshot:



That version is a fake and/or some kind of scam.
Microsoft do not and have never used a Nullsoft installer for Messenger. (I'm not saying there is anything wrong with the Nullsoft installer, plenty of good programs use it. I'm just saying Microsoft would never use it since they have they're own installer.)

Get Messenger directly from Microsoft, it's the safest way to get the real version.

But I am still STUCK. I get a MESSAGE box saying
