TOPIC: How to Disconnect my Facebook Account?

Hi everyone! I have 2 different Facebook accounts, and I noticed that I dont want to use the one I already added, but Instead I want to use my other facebook account! I did disconnect the APP from my Facebook account, but on my FanSlave account I can still see that its connected to my old Facebook!

I then tried to login with my NEW facebook account, but then I was told that its a Wrong Account... I am really exhausted trying, and I do not want to use this FAcebook account.. how to completely disconnect it from Fanslave?

Thanks a lot in advance
