I have recently rebuilt my computer with new parts and have a clean install of Windows 7. So I started fresh by download Blockland again and transferring my saves and add-ons from a flash drive to my new Blockland folder. When I first opened Blockland it was windowed so I put it in full screen and restarted it. And when it came back up again Blockland turned black and minimized itself, however the prompt was still open and I could still try to open it again but it will just keep minimizing itself. After this I restarted the computer and started Blockland back up and for some reason it worked just fine, however later on today this same problem occured now and it just opens I see the start menu briefly and then it goes black and minimizes. If anyone has experienced this problem or could help that would be great.
