Hi! I recently installed minecraft and after getting the hang of it my boyfriend suggested to download a mod to make maps quicker. He guided me into installing forge and then the map making tool mod (so I could copy/paste stuff, delete stuff, set blocks and whatever else), I followed both his and the site's guidelines but once I tried to start the mod, it wouldn't work at all. It only crashed and gave me a crash report, which I'm going to copy here to let you all understand:

At first I thought the mod was faulty so I tried to download different mods but it gave me the same exact error. The launcher just stops loading after a short while. I even tried to run the launcher from a different folder but while the game opened, the mods weren't there at all. I tried to search everywhere to understand what I was doing wrong but no one seems to have this problem. I only wanted this mod so I wouldn't spend ages just to make a castle on Minecraft in creative mode but apparently it's harder than I thought. Can someone please help me? I've been trying to make this work for days now.

 

P.S. I apologize if this is the wrong place to put this topic. I hope I read everything right though.

Ok after doing so the game loaded, thank you a lot but it seems I can't use the mod yet.. I'm in creative mode, cheats abled, checked if the mod was abled and it is, but I can't use the wand. Neither any of the cheats of the mod, can't really understand why. Like to use the cheats of the mod I need the wand (which, in the mod, is a wooden axe), but it just doesn't work.

 

EDIT: Ok after searching through stuff I finally found the problem so it's solved, thank you anyway a lot!!
