Sounds like you have the same problem as me where uptobox is concerned. All you need to do is wait for timer to countdown on free download and click download when ready then you will get pop up which you will need to close to access start free download option that you click and just minimize the next pop up that comes up. Just ignore the spam sidebars and you will see your download in the circle top right to view the progress. Works for me from VM site. Just make sure you have winrar or izarc installed. Hope this helps.
