I downloaded the latest version yet I can't load my last save file.
I've tried moving my old files into the new folder but can't play it.
Is there a specific step(s) i need to do if I want to play my old files with these new updates?
I am going to assume you are talking about the newest version of the game, 0.25, and not talking about the launcher.
However, if this is the case, the above makes no sense. There shouldn't really be a new folder, because the launcher will download the update and place it in the same folder as always. The updates will be placed in the Pokemon folder, a subfolder in the folder where you placed the launcher. Exactly what have you done here?
As for resolving the matter
Any chance you have edited any of the game files?
What happens when you try and load the game?
I can suggest a couple of things, but I need more info
