Can anybody confirm whether this "debian-m5-v3e-Sci-2GB.img.ext2.lzma" is corrupted or not?

I get

xz: debian-m5-v3e-Sci-2GB.img.ext2.lzma: Compressed data is corrupt

I have downloaded it using wget. Took 3 nights to complete. (Used Profilematic to schedule auto dowload via wget coz of slow internet connection and night data allowance)

Actual file size is 486MB but the downloaded file is 604MB.

Hope someone'd help.
