Problem with NGC Ikaruga

I've downloaded the game Ikaruga for GameCube but I can't extract the iso file from the rar file. It makes an error when I extract it.Can anyone check this?.

Did you check if the file has the correct size?

I don't remember right now but I think it had the standar size for the NGC isos (1.4 Gb aprox), but the problem is that I can't extract it from the rar file.

It might have gone corrupt.Have you tried using a download manager?

What you mean with a download manager?.

Download Manager is a program that helps you to manage any kind of downloads,
It can also prevents any downloads to be stopped which can make it corrupted.Example of download manager are..
- Flashget
- Orbit Downloader
- Free Download Manager

I downloaded the game 2 times and always give me the same problem. I'll try to download it with the jdownloader (i used it a sometime ago). Can you explain me how to download the game with jdownload.Thanks.

I haven't tried Jdownloader, but I found a basic tutorial for you,

With most managers, right click and chose the "download with [INSERT DOWNLOAD MANAGER HERE]" option.If the download stops, pause/stop it and try the resume option (it looks like a play button on some)
