I can't share songs on twitter and twitter doesn't even appear on 'social' options

[issapm]

I changed my password and erased all the apps that could use my twitter account. Now when i try to share music on twitter through Spotify it appears a message "error, there was an error posting this item".

I've tried to log again into the twitter account through spotify but the twitter option doesn't appear on the social menu (it only shows facebook and lastfm).

Please help!
