EPIC Launcher rework needed!

This is still a problem.

I left the Dev Kit downloading all of yesterday which allowed me to download approximately 70% of the required files. Last night I turned my computer off and today when I tried to resume the download, the stupid software is unable to resume. To continue, it is still tying to find the total amount of free space required…however is it completely ignoring all of the previous files that were downloaded. The first image below shows the current DevKit size, the second image shows the error I’m receiving while trying to Resume.

What’s the point of a Resume button if it doesn’t even work???
