MMH5.5 - Heroes of Might and Magic 5.5

I understand. Try this:
- Go to <game directory> / data
- Delete index.bin and the RMGTemp folder, if it exists
- Open the editor and see if it works

It works. Thank you.

And I understand that the game has recreated both the folder and the file.
Should I restore the old ones?

P.S. I don't know if I need to, or where to report game bugs... but:
1. The witch hut bug still hasn't been fixed.
When the "8 secondary skills" option is selected for the hut, you can't learn the last 8th empty slot. (If I remember correctly, you can upgrade the skill)
2. Magic luck doesn't work on the "stopping chill" spell.
