Alright so i have this problem..

I tried to add a new contact but accidentally put the wrong name, okay i thought: "let's just delete that contact." but i wasn't able to delete it neither block or anything else. If i click on the contact it sends me to my browser and opens the main messenger live homepage. The main problem is if i try to add the right address msn tells me that i can't have this contact twice in my list. (To clarify things, i wrote ".de" instead of ".com") So i would like some help on this problem, i found no solution on google or anywhere else..maybe i searched with wrong tags. Ty for your time.

Go to live.com then enter with your MSN account.

Now click in Contacts on the Messenger label in upper bar. You will see your contacts. Search the contact added then delete her checking the box and clicking in delete button.
