For some reason I can't download 9D on my computer. It downloaded perfectly on my laptop. I tried using Chrome, Firefox, cleared cache and cookies on both of them, reset my internet and I'm still getting this download error.

I got it to work. Avast (my antivirus) doesn't like 9D so I disabled it while downloading. Thank you though!
