Ive been working on a game for a few months now and the last time i opened it there was a problem it said "Unexpected file format." so i tried opening the application and it had no problem (i know that doesn't change much). Then i tried making a new project but instead of creating it, it said "Failed to create folder." so i reinstalled rpg maker xp an still couldn't open or create a project and so i tried three more times (by uninstalling then trying again) and still didn't work.
I would love some help, and thank you.
Edit: Sorry if i have bad punctuation and or gramer.
