I was able to play the game on one computer fine and wanted to transfer my save to another. I didn't have much time to figure out the required files so I just saved the entire 'storage' folder. When I finished installing the game onto the other computer I moved the contents of the copied storage folder into the new one and ran the game - without having previously launching. Straight away an error popped up with a "Fatal Exception caught: (IOException) could not change directory to \Device\HarddiskVolume3\Steam\steamapps\common\Starbound\win64\" - . It seems like a non existent directory. The first thing I did was delete the storage folder and create an empty one with the same name. Same error message. I then deleted local content and reinstalled. Same error message. Restarted the computer. Again same error message. As far as I am aware there are no exact same error messages in other threads. Even the other 'IOException - rename error 3' solution didn't seem worth trying. Currently the storage folder is empty. Any help would be greatly appreciated.
