Why is this happening to the file at slicer?

[Unfated]

The file is from thingiverse and several of my friends have printed it with the same printer with the same software.
It's separating the file into two parts, and leaving a blank area.

The most likely problem is issues with the file. Run it through a checker such as makeprintable.com to make sure.

Thanks I'm trying that now. The file worked fine for my friends.

It's great when an easy fix actually works!
