So I just downloaded DMMD today because I was curious on the whole context of it and what not. Anyways, I followed all the instructions from this blog and everything worked fine at first. It started up but it went straight to full screen and since I didn't expect it to open at full screen I quit the game. Well now whenever I try to open it there's a plain black window that will open for 2 seconds and close. I changed the local to Japanese but for some reason it's been switching from English to Japanese back and forth. I even viewed other forums relating to this topic and I can't get anything to work. By the way I'm sorry if this is in the wrong section. I'm new to this and I usually don't use forums so yeah.
