Can you be more specific, don't just say 'I CLICK ON IT AND A BOX COMES UP AND THEN I CLICK OK AND NOTHING HAPPENS'
I am sorry I re-read the question slowly, I Obama'palogoze.
The error reports on PC's generally mean that your computer couldn't handle Blockland in some way(I think)
5 ways I think you can get the PC error report
1.) Your Video card isn't working/or it sucks
2.)A bad Add-On
3.)It's too much for your computer itself to handle
4.)You installed the game wrong(which I doubt, but there is always the odd one out)
5.)Or you messed up one of the main scripts(again I doubt that, but there is always the odd one out)
