I bought securitales, a vpn service for my stay here in china and it works pretty well so far. I want to download megaupload files but whenever i load the site and press the download button, the page loads to a blank page and nothing happens. Any solutions?
Securitales is not a VPN, it is a proxy and suffers from the flaws all proxies have.
Use a real VPN like http://www.surfbouncer.com and you problems will go away.
