How do I get refund for error-infected game downloaded from Yahoo the Microsoft says to be removed?

Attempted to play Scrabble; only game up on trial page asking if I wanted to purchase which I had already done; computer locked up with error message saying to remove newly loaded software (which was Scrabble game). Had to shut power off to get the computer back up and running.How do I get refund for error-infected game downloaded from Yahoo the Microsoft says to be removed?I'll bet you're running Windows Vista. They haven't updated the software for running on Blista. If so, a banner appears that tells you that the game is not certified to run on Blista. Not reading the System Requirements tends to not lead to refunds. Having worked in the PC games industry for nearly 10 years, I've seen this plenty.
