1) Minimum payout $50 = way too high
2) Your premium prices are way too expensive compared to other hosting sites.
3) Downloads aren't being counted (I had 4 people download a file and it shows 0 downloads and how convenient, a bug that isn't counting downloads)
4) Malware issue popping up from people visiting your site

You're on the road to success!

Also you should add an option to remote upload from hosting of users choosing or at least add more hosts to your list (such as many found here in this section). Many of us aren't happy with some of these new hosts and would like to remote upload our files from them and stop using them.
