it seems you have a different version of the game (in english version you must hold shift +~ to bring up the text box)
for last quest i can say that ink is just a normal artifact lvl 1 item, the item code is inkpot.
code: "item inkpot" without quote (well i destroyed my two inks to get some crystal and i used the cheat to get the ink
)
and quest log dose not update even if you have both ink and paper in your inventory, however you can finish the quest if you have both item and talk with the quest giver, (take note that there is no quest sign on professor house, nor on rezo tower).
