My old FALCHE2 won't work, it always shows the error message of "Character data (main1) not found." when opening the slot. Can anybody help? thanks!

sorry, push the wrong button, how to undo the solution mark :)))

I'm not sure? Maybe contact support and see if they can undo it.

Thanks, Skreczi!

Out of curiosity, it tells me now that it can't load my save game because I may have saved it in combat mode. Actually, I wasn't in CM but sitting still in New Reno. Any ideas?

This might be due to a bug in 0.4 with the first 14 items in the game. If you have any of them, the save game might not load (incorrect parsing leads to the combat mode message) . Try 0.5 - and if you have any problems please use the report error feature to let me know!
The list of bugged items is:
1. Leather Armor
2. Metal Armor
3. Power Armor
4. Knife
5. Club
6. Sledgehammer
7. Spear
8. 10mm Pistol
9. 10mm SMG
10. Hunting Rifle
11. Flamer
12. Minigun
13. Rocket Launcher
14. Explosive Rocket
