submission of PC games are impossible

when i try to upload a PC game, the website logs me out. i move the mouse every 2 or 4 minutes but it doesn't matter, once i log-in again, it removed the 100% zip game file that took 2 hours to upload. what's it even worst is that it randomly makes completed form into penning, this happens even when i didn't do anything to it. please someone fix this annoying bug.
