numeric number of seconds to wait for web pages
to load when finding the download URL on
Protected Planet.
Defaults to 2.
Since the process of finding a download URL requires

the default argument means that the function will take at least 8

containing the message Error: Summary: NoSuchElement).
To avoid this, users can try specifying a greater value (e.g. 5 seconds).
