I am sorry for that issue mate, but there are many other people that upload 2h or even 3h sets to DSound. It has to be a problem with your setup, network or any other thing... And if I didn't get back to you, sorry for that, but you should be retrying more, since I have been really busy and some things get lost in the way... Let's continue this on Discord #support and see if we can find the problem.
