RapGet Download Manager
RapGet doesn't require Java, supports 50 languages, more than 60 file hosting sites, and doesn't spit out German text at you when the language is set to English.
The program doesn't attempt to get around download limits in any way. If you have a paid account with a service like RapidShare, you can use RapGet to manage your downloads. But you can also use it with free accounts. It will automatically enter CAPTCHA codes for you, download one file at a time, and wait a specified period of time before attempting to download your next file.
