Yah. I dont get why you had to buy it 5 times. If you want to use your account on another computer, simply go to the games section and double click on one of the games. It will download the game onto the computer and install it, so you dont need to buy a new one. I think you should drop valve an email. Its not in their policy to do something about it, but if they value their customers the least bit I think they will make an exception for a poor guy who has 4 HL2 games on one account...
