Pretty sure you need the DG disk to install initially. I did a pretty big update for the game, with icons and such, email me and I'll get you the files. I have the whole game on Dropbox, but pretty sure you need to install off a disk first.. Although, I have a nocd crack exe as well, so maybe just try this? https://dl.dropboxusercontent.com/u/58654449/DGVN.zip
If it works, let me know, and I'll get the update files to ya!
