How to delete my halfway translation of an existing subtitle

[saru]

(At first Sorry for my bad English.)

This one.(Japanese)=> http://www.addic7ed.com/serie/All_Hail_King_Julien/1/9/The_Really_Really_Big_Lie
(It is all me."saru@sub-talk.net" signature in the first line.)

Initially, I did not understand a how to upload the translated version of the existing subtitles.
I got a wrong operation.　I entered the editing screen.
But, I challenged it. 
And I realized it is very troublesome to write by one line at a time,  and handling is difficult for me.
I want to delete all it, but I not understand how to do.  Please tell me how to all delete.  I reflect!

I understand you wish to delete your own ongoing translation and upload your completed subtitle.

I have deleted your work.

Please, upload your file clicking the "upload new version" button.

Cheers

Alice.

Thank you Alice-San! Thank you for the time and effort.
By the way, unless we ask in the forum , we cannot delete own sentence and own account?

You cannot delete a translation in progress, saru.
Even if you started it.
Yes, you'd have to ask...

I see. 

Thank you for many times.
