Amnesia custom story glitch?

[Storfigge]

So I've been working for a while now on my CS and it's going great and it's really fun. I first made this custom story last summer but gave up on it because i didn't have the patience to learn the coding :/. But about a month after that i moved it to my laptop and decided to give it a second try. Now my laptop isn't really the best computer out there so when I try my map it lags a lot especially now that I've made a few bigger rooms. So I moved the CS back to my better computer so i could test the map there without any lag and maybe work on the CS on this computer sometimes. Now comes the big issue... Once I've moved the map via a flash drive and started it, it looks EXACTLY the same as it did a few month ago during the summer... All the hps and map files are in the correct folder and all my coding is there but for some weird reason neither my Amnesia nor HPL editor can load the map correctly? It just looks like it did before?! I've tried pretty much everything that I can think of to fix this but noting works? So if someone knows what's wrong please help me
