ufo aftershock

how do i unblock starforce protection driver?

i recently got the game ‘ufo aftershock’ on my pc but i cant use it. it says that ’starforce protection driver has been blocked due to compatibility issues’ my friend says i can unblock it but i am not sure how… help!

This is from the starforce site:
http://www.star-force.com/support/drivers/

They know of incompatibility issues with the driver, and provide solutions, driver updates & more. including removal.
