as in my first problem, this has only come about since i was forced into re-installing both messenger and msgr +.
when i try to block a group, it says the "group name is invalid !"
despite me changing the group names, and making new ones, it will not let me block any group :/ i need to block some groups as there are people from school who just want to chat whilst i am trying to relax or doing some work.
