Hi, I bought a student license for PD8. I'm wondering if there's any restriction of usage/ 1. May I use it for commercial activities (e.g. develop commercial software in Windows in PD). 2. If I graduated, can I still use it? 3. Is there a discount on upgrading? 4. If I bought the PD9 upgrades, does my license still remains in student license or it automatically switched to commercial license? Thanks you guys !
