Any idea where my Familiar might be?

Hello Everyone! I'm playing BGT; and at the end of BG I had a familiar summoned. When BG2 started and I was at Irenicus's dungeon the familiar wasn't there anymore. Now when I try to summon one I get this message: "familiar has already been summoned" Could anyone please help? PS:If it makes things easier; I've included a savegame with this message, maybe it might help.
