When I try to extract a nds file, this happens...

I use WinRaR and when I tried to extract Bowsers Inside Story and Kingdom Hearts a diagnostic message popped up saying an error occured and had three exclamation marks with 3 messages saying how it didn't work. It has never done this before, only for these two roms. What's going on?
Thanks in advance.

I can only guess your download got interrupted, corrupting the file. Have you tried re-downloading it?

Try using a download manager to avoid this in the future.

What's a download manager?

It's a program that will enable you to resume a file instead of overwriting it, so if your download gets cut off it will just finish it instead of downloading it all over.As our introduction guide specifies resuming a download never costs points.

i havent had a problem like that. use jzip it does rar zip 7z etc...

Using a different archiving program will not fix a corrupt download, don't confuse the issue.
