[Druid] Request to take down my paper at DRUID 2018

Dear Sir/Madam, Could I make a request to take down my paper at DRUID 2018 (https://conference.druid.dk/acc_papers/j3hkhnds0y112f4m017sb32hxd29p2.pdf), because I was planning to submit my paper to a journal and it requires it hasn't been published or publicly accessible? I once sent you an email about this issue but I have not got reply. I am going to submit by the end of this week, so I must send the request again. Sorry for any inconvenience and thank you. Regards, Yuni
