Fix indentation error and prioritize 5stems model

- Fix IndentationError: expected an indented block after 'if' statement
- Change priority back to 5stems model first (as requested)
- Keep 2stems as fallback if 5stems download fails
- This should resolve the runtime error and use preferred 5stems model
