Remi, GreeZ,
I found the problem. There's nothing wrong with resume/pause mechenisism of this plugin. The reason is i'm using free download of megashares.com and it has limited at 550 MB/each and have to wait 120min. This plugin didn't raise message [Limited reached] and start wait timer (likes megaupload) but [Plugin error - out of date].

Please help to change the description in BugTracker ticket.

Thanks for you support.

Duy Doan
