Mac MSN -> Message has not been delivered

I have downloaded MSN version 7 (2009 I think) on my new Macbook Pro.

Every now and then, when I send a message, a few minutes later I get a message saying "The following message could not be delivered: ___."

How do I fix this?

 

MSN redirects you to a page to verify you're human and not some bot sending spam email's, your browser might be blocking the link where you have to put a security code to verify you're not a spammer and that's why you get "Message has not been delivered".

Try a different browser, if this doesn't fix it, you will have to google hard im afraid.

 

I am talking about the messenger. Also, this happens to people who have added me and I have added them back in the middle of a conversation.

 

There is a mac in my house but only my sister uses it, i barely use it so i don't know much about macs, but this has happened to me before like 2 years ago i used to have this problem, reinstalling messenger fixed it for me.

Make sure you have the lastest version of msn messenger for mac. If reinstalling the current one make sure you re-download.

If none of that works, you can download adium http://adium.im/index.php it works with msn.

 

I tried Adium and I did not like it. I don't want the latest version of MSN; I want to keep this version as I know it best... however I may try downloading the new version tomorrow.

Thank you very much for your input!
