Ouch. Sounds like you had a lot of trouble...

Without repeating advice, I can only say that when I purchased Fish Tycoon, the charge came from Trymedia. I believe I downloaded it from MSN Games. Shockwave.com would show up as shockwave.com on a bill, and yahoo would show up as yahoogames. Big Fish games would show up as big fish games, not Trymedia.
