I don't succeed in downloading a series of rar's.

Example
http://rapidgator.net/....part1.rar.html
http://rapidgator.net/....part2.rar.html
http://rapidgator.net/....part3.rar.html
http://rapidgator.net/....part4.rar.html

These files are 'translated' into
http://rapidgator.net/file/1e06b2615...part2.rar.html
http://rapidgator.net/file/3a86ce369...part3.rar.html
http://rapidgator.net/file/56f47a42c...part4.rar.html
http://rapidgator.net/file/afa7aa842...part1.rar.html

But the downloading is almost immediately 'completed' and each downloaded file is 24 KB.

I know there is a solution to that, but I can't find it.
