Patching

[Nybris]

Ok, just purchased the game and I can't get past the stupid vines spitting without crashing. I know that there is suppose to be a patch for this, but where?

I've tried searching the internet for a site that I can download a patch and the only one that I did find a patch for immediately made it so that I need to enter a serial number, that didn't come with the game, to play.

I purchased the game King's Bounty Armored Princess with the bonus expansion King's Bounty Crossworlds at Walmart. There are no inserts, no manuals, no activiation codes.

Where can I get the correct patches for this game or should I just take it back and get my money back?
