HI,
Lets try removing them then.
With Messages Quit....
Enter the Preferences Folder via the Finder > Go Menu > Hold ALT Button > Select Library method.
Drag the following to the Trash:-
com.apple.ichat.plist
com.apple.ichat.AIM.plist
com.apple.ichat.Jabber.plist
com.apple.ichat.Subnet.plist
com.apple.ichat.Yahoo.plist
com.apple.imagent.plist
com.apple.imessage.bag.plist
com.apple.imservice.iMessage.plist
Leave:
com.apple.iChat.LSSharedFileList.plist as this deals with the Recents List of recent past chats.
com.apple.iChat.StatusMessages.plist as this deals with the Custom Saved Status Messages.
In the Preferences find the "By Host" folder
Drag any item with com.apple.ichat.... .plist (And a Hexidecimal number) to the Trash
Restart Messages.
