Megaupload did a large update yesterday, they have seemed to implement a new uploading/downloading system, therefore users will not be able to upload with this program but i am sure the admin will address the issue ASAP. So no need to worry guys!
Everything perfect but the premium link grabber tool does not work with megaupload, I have premium account there and will not leave me all the same links this: http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd
