Help change

I am having problem before it appeared to change the email of id.net and now it is not showing up anymore because? and I have already changed the email once and now sometimes when I enter the old email appears because? will be that inda is bound, if you want to unlink and put what I use now, since I need to play drakensang online. From what I read in some posts need to update the database of you? I just want to unlink the old email because I wrote it twice for the id.net support and they do not respond, there is no notification in this new email that I put
