Hey, which platform and device you are running?
If you have trailer access you can only stream/download trailer, and if you purchased the video — you'll access full video streaming and download.
If you are running windows system, please repeat your steps till you see "Loading something awesome...", quit the app and send me output_log.txt from the folder where Sexlikereal Application installed.
If you purchased the video but can't download full version in the app, can you check if you have full access to the same video on the website? (log in with same credentials). There is no pay for downloading video — once it's purchased you own it forever and can stream/download without any extra charges.
