I just loaded it on my laptop perfectly. What browser are you using? Firefox is the one I used, and it loaded quite quickly, no white screening.
Some games do not load if you are using VPN, so make sure you turn off any VPN connections before trying to load up the game. Also, your computer could have not enough vram (I believe flash games use this) to successfully load the game. The laptop I loaded it on has 288mb of vram, so check to see if have more or less than that.
As a last ditch effort, you may want to try contacting support for Battle Pirates at
They should respond to you and will probably be better helpers at fixing the problem than I am.
