what is your your problem exactly are you able to install it and run it and your controllers are not being reconized; or is it such that you are unable to launch the program at all where is the problem?

where are you accessing from are you on your home network? is it you school? you could manualy change your Domain Name Service (dns) to a server you pick because that seem like a dns block for more information on a dns try this video https://youtu.be/Rck3BALhI5c

you might want to try www.handbrake.fr its an open sourse video transcoder (changes all the information from one type of file to another)

I tried to look up who registered their domain (the address) and all of the information aside from their registration dates, the renewal date, and the expire date were "REDACTED FOR PRIVACY" so that's not much of a help sorry.
