Why were you trying to buy HYIP scripts in the first place? You do realise that they are essentially just another name for ponzi schemes, right? And it's illegal to run a ponzi in most jurisdictions, I believe. You need to stop running or attempt to run HYIPs right now.
But addressing this scam, remember that for every purchase you make on the forum, always use an escrow. If you're not protected by escrow and keep sending first you'll continue to be scammed.
