Too many msn contacts

Whenever I go to add someone or accept their request it doesn't work because I get the message that I have too many contacts. I have tried deleting multiple contacts but no matter what I keep getting this message. What can I do?

 

No way I know of to fix this other than to make a new MSN.
Use A-Patch (http://apatch.org/) if you want to stay logged into both MSNs at the same time.

Hop to Skype and use it when you can. Skype does have any similar bugs. I am using MSN by myself only when it is really needed.

 

I use Gurtaton's method. It also helps you to juggle private life and online life without having to use the same MSN.
