I am new to FreeRapid and using FreeRapid 0.83 on my vista machine. I found that after I downloaded 3-4 files from megaupload.com or any other download sites, all the http requests from my machine will fail. If I try to go to any URL using FireFox or IE, all it returns will be an empty page. I can only restart my machine to fix this problem. Is this a normal behaviour? By the way I am running Bitdefender 2010 on my machine.
