The definition for the OA library "Animate_Cache" in cds.lib specifies a location without a parent directory.
You can fix this issue in one of the following ways:

• Create the directory tree where the library is to be created
• Change the target location specified in cds.lib
• Delete the definition of Animate_Cache in cds.lib. Animate Preview will add a new definition to cds.lib and create the Animate_Cache directory in the current working directory.

Then, re-run Animate Preview.
