cannot add a jabber account to messages
somehow my Messages is having a problem, I think I deleted something related to jabber, when I add a jabber account it won't show in message even though I can see the account under accounts in preferences. I noticed that com.apple.iChat.Jabber.com was missing from library so I copied it from another mac but still did not solved the problem. Any idea?
This is only happening for jabber or google accounts, any other account works well (yahoo, bonjour or iMessage)
Thanks
