In the production process of the acoustic shadow, the material has been loaded, you can not rename the original file, move the path or delete, rename the original file, move the path or delete, it will prompt "the original file does not exist".
Because, the files loaded by Acoustiguide are not directly put into the software, but take the linking method, so once the original file is renamed, moved or deleted, it can't be linked.
Solution:
Delete the loaded file and reload it.
