Help on to extract files on Winrar

Hello, I downloaded a few games on this website; the downloads went quite well...
I quiqly downloaded winrar to extract the files : and some don't work !
The firt game that I extracted was "Yoshi's Island" and that went well.
The second was Mario & luigi Bowser's inside story and It said " Error...file corrupted"
And many other games like that !
Does this mean that I can't play the game ?
Please can you explain what to do ( in SIMPLE words please ! ).Jackyboy67PS : Sorry for my bad english

Wow, be patient! People aren't gonna help you if you pester. It just sounds like the files are corrupted. Have you tried re-downloading them? Give that a go and tell us if it worked. And next time, wait at least a day before bumping the thread.

Haha,
Be patient Jacky boy! ;D*ahem*
Try using a download manager next time when downlading,
The best one that I found is FlashGet or maybe the OrbitDownloader.

''Many other games''? Some of them might have anti-piracy in them, usually theres a fix.

Sorry for being impatiant, I redownloaded the games and now they extract !ThanksJackyboy67
