Creciever.ino example build error

[electricsix]

I'm probably missing something, but having had issues with my code I started again with the provided CANreciever.ino and am having the below issue;

I've changed nothing, so why doesn't this work? I've got the library installed.

Looks like I changed from <> to "" on the #include line, but this makes no difference (or at least isn't the cause of the issue)
