There are thousands of people who were able to download Sia and get it working. And on average they have uploaded less than one file each.

I'm sorry that you are having troubles, but if you refuse to help us figure out what the issue is, we can't improve your experience. Maybe you should come back in 3 months. The beta is working fine for many people, and we are grateful for all the help that they have given us. We couldn't have gotten this far without the mountains of feedback we've received so far. And some volunteer developers have started making non-trivial contributions to the proejct, which is going to help significantly in the long run.

I for one am going to focus on building Sia for the needs of the people who are most excited about it and willing to tolerate all of the turbulence associated with the early stages of the product. They are the users who are most important to me, and they are  the ones who will get their feature requests prioritized.
