First, let me compliment you on your work. The mouse interface on Gehn Shard is much smoother than on URU-Live. I don't know why, but it's a pleasant surprise.
However, my installation keeps crashing. I downloaded the installer last night and attempted the install. It took several tries and several repairs but I got it to boot. Now I can get to my Relto, but as soon as I attempt to link to the Cleft, my game crashes and I receive the error message telling me that the file clftZandiRadio_Loop.ogg is missing. When I look at the installation files, I find that it is indeed missing from the sfx folder.
I click on the repair procedure in my Windows 10 start menu and it begins the repair. It downloads 7.22Mb, then a .666Mb download. Then I'm given the log in screen. After that, I see the Cyan intro and another download of GUI district files. Once I choose my player avitar, I get to my Relto. But as soon as I attempt to use the Cleft linking book, the game crashes with the same message again and upon inspection, the .ogg file is missing again. I can do the repair again, but the process repeats itself. By the way, after the repair procedure, the .ogg file is back in the sfx folder, but when the game is launched and crashes, the file is gone again.
Fyi, I can use my Neighborhood book to get my KI and return to my Relto, but attempting to use the Cleft book results in the error again.
