So my system just suffered a major HDD failure. Luckely I had a fairly recent backup. So I reinstalled everything from scratch with FC10. My problem now seems that, hydrogen just refuses to start. I click on the icon, it appears in the task-bar but no splash screen, no window. Then it just goes away. No logs, no messages, no errors, hydrogen.log completely empty in my profile... nothing nowhere. Just won't start. I uninstalled, reinstalled, compiled from scratch, removed, switched versions... nothing seems to work. Just won't start with no explainations. Anyone ever seen this? Thanks. Pat.
