Hi there,
Followed the quick guide on the wiki. Set the profile to just be my normal armour, tools, food and rockets. I open the profiles.txt file, I change the name to "Gear", save and close the file. When I hit R + Y, I get this error:

attaching the config would help

Oh yeah true, my bad!
profiles.txt

looks like the HEAD slot was added by hand and all the enchantments are missing the "minecraft:" namespace

That's bizarre. The only thing I changed was the "Saved" keyword to the name of the profile. I added in "minecraft:" before each enchantment and it works now! Odd one, but thanks for your help! Fantastic mod!
