| Issue | Impact | |-------|--------| | | No native macOS or Linux version; requires a Windows environment or virtualization. | | Limited Multi‑Language Support | Only English interface and lesson texts; non‑English keyboards need manual configuration. | | Serial‑Key Activation | The software still relies on a traditional serial‑key model, which can be cumbersome for schools managing many licenses. | | No Cloud Sync | Progress is stored locally; no built‑in way to sync across devices or backup automatically. |

If you’ve already bought the software but misplaced your key, reach out to the developer’s support team. Provide proof of purchase (order number, receipt, email) and they can usually re‑issue your serial key.
