I can't install this :S

Im having a few problmes with this too! the keygen says

Before installation and updating vBulletin you must:
1) Check the release with validator.php to make sure, that is clean
and safety
2) CHMOD all files 0777 to write the new data in them.
3) Execute keygen.php
4) Remove keygen.php from server after genering and enjoy.

Or just use our release without keygen.

WARNING: DON'T FORGET to return CHMOD back beforе start using your
forum. It's safety requirement!
