File Unknown Type/Damaged

Good morning,

It's been a while since the last time I played WoW in Warmane and I really miss it, so I went to Warmane website to download it again.
After a few hours waiting, my download is completed and I wanted to extract the file (file name is World of Warcraft - Cataclysm 4.3.4 (15595)), but I can't because of the file is unknown type/damaged, and there are only 3 files (1 folder, 2 files) inside the .rar, which is Data folder (there is only one file inside it which is art.MPQ), BackgroundDownloader.exe, and Battle.net.dll.

I've redownloaded it and I got the same result as expected, well I guess to repeat the same action and expect different results is madness. Heheh.

Please do help me if someone know other download source OR a lot better options how to fix the file without redownloading it again. Thanks!

go here: http://forum.warmane.com/showthread.php?t=201017 and click on "download 4.3.3". This installer allows to play and download the game at same time
