flash plugin sha256sum mismatch

[glederfein]

Hey all!
I'm using ubuntu 8.04.
I can't install the flash plugin.
I even tried using the "Main Server" but I still get the following error message when trying to install:

sha256sum mismatch install_flash_player_9.tar.gz
The Flash plugin is NOT installed.

Thanks in advance.
