not able to load maps

[Kman]

so for the last few days i've been working on a map for my custom story. just today i went to edit some problems i found and when i hit open instead of bringing me to the amnesia/resources section it brought me to the main finder page (so it's displaying like "applications" and "desktop" instead of the amnesia resources folder that it normally does). i've tried getting there from the applications folder but whenever i try to open it it just says "file does not exist, please choose a valid file". so because of that i can't edit my map at all or start a new one for that matter.
