new messenger

downloaded new version 3 days ago and it has been nothing but a hassle…i
cant see my contacts so dont know who is on line…or if I am on line. I am
very disappointed with the new version and saw no reason for upgrading.
All of my contacts from last version are now on the version 4.0 …reverse
tactics or what. Needless to say, if I cant soon get messenger working I
will be uninstalling and staying with Paltalk
