Thats the drop box link to my Dayz file that you guys wanted.

I found the file but I don't know how to upload it to the website. It won't let me drag and drop,when I try to go through the upload file thing it just open the file.Do you need the whole file or just something inside of it?

"in case you are using any startup parameters, remove them as they cause various issues within the game such as crashes and freezes". Im not to sure what that means sorry :/ Anyways thanks for the help!!!
