Issues and solutions
Problem: Nothing happens when you press Ctrl+N
Solution: Make sure you installed the script, also make sure that ScripthookVDotNet is working
Problem: Script asks for activation
Solution: Activate the script using this blog post
Problem: Script stop working when you choose a armor
Possible solution: Update your ScripthookV and ScripthookVDotNet
Problem: Armor don't appear, some weird objects appear instead
Solution: Avoid game updates or use the mods folder idea
Problem: Armor parts are distant from player char. (wrong offset)
Solution: Use the .ini armor file that goes with the armor, if problem persists replace the commas with dots in the numeric values of the armor .ini file, example: from 0,25 to 0.25
