Simfiles downloading wrong

[Afrobean]

I'm having trouble with the simfiles. Almost every time I download one, my computer says it's not a valid archive and it says that I should re-download it. That doesn't help. I've tried not using download accelerator and just downloading using Internet explorer, like many people here have recommended, but it doesn't help me. Is there any other program similar to download accelerator that is sure to work.

download accelerator isn't the problem...i don't see how it could be anyways.

Try the oppisite you have: WinRAR/WinZip

I only have winzip

Well that's your problem. Zips that have been made in winRAR using "best" compression mode can't be opened with winzip. Winzip sucks anyways. get RAR
