cant activate game

[techstepman]

im trying to play star wolves 3.

i click on the desktop icon and im said to put in the serial number.but then it says that ive already activated the game.ok so next i click on i already have an activation key and its says "error put in serial number"...cant really understand whats happening.

i used to play this game on my old pc.since the product is activated why should i re-activate it?

can someone help me?for some reason this turned out to be a lot more difficult than its supposed to.i checked with search and i didnt find anything related in the forums.i googled the web and still i couldnt find any solution to this.

does this game get activated only for one pc?if this is the case how do i deactivate it from my old pc thats in the garbage?
