use the same save in the same modpack but changing from cracked to original

[Silveer]

I was playing the "azuria rockblock 3" modpack but I still didn't have the original Minecraft so I played using a pirated version, I only recently managed to buy the original version, but when I downloaded the modpack and used the same save as before, in singleplayer , I lost everything in the inventory, I lost access to chunks marked by ftb chunks, also from AE2 and etc..., in the "playerdata" folder there was the old UUID, I tried to just change the file name to the new UUID and when I entered in the world, I still didn't have access to anything, I tried to use NBTExplorer to modify the .dat and even so I still didn't have access to anything Could someone help me PLEASE
