Hm... Looks like I rushed posting this. I can't confirm that this works... The internet tells me I should drop down in the volcano in the cleft to link to Myst V ages. So, I jump over the fence run up top and drop down, and it just spawns me back at the cleft....
Originally, when I tried importing my GOG version, the DI Launcher deleted them, since they were "wrong", so I tried the retail version, and I thought since DI "swallowed" it, that was proof enough the data was good. But after posting this, I've been trying to link to those ages with no luck, DI or Uru offline, both drop me back at the cleft.
So, I can't upload the patch unless I'm sure it works. BUT! If anyone has a retail version, which they're sure is the right one, I can send over the project files. All you have to do is point the program to the "old" and "new" data directories, and click a button, and it will spew out a patch, it should be no bigger than 2MB.
So, please, tell me if I'm doing something wrong, or if I just have the wrong version.
