[Laughter Land] problem with extracting its files.

[InfiniteX]

I've downloaded the files, joined them in hj split, and I get this diagnosis
message as soon as I open the rar file. "unexpected end of archive" "CRC failed in Laughter Land DISC\IMAGE\.img. The file is corrupt". (That message showed when I attempted to extract files. I am using Winrar).
I've also downloaded other files from different sources, and the result still happens. Any diagnosis?
(This is the first time happening to me after successfully downloading other BL games :c.) Much appreciated .
OS: Windows XP

It should be a problem with the links. You can download them here, these links should be fine (depositfiles)
