I try to open up my Paintstorm Studio application but it just comes up with the text box "Application cannot load icon". I've had this problem before and it's always after a file corrupts, I just lost a piece I worked really hard on because of file corruption and now this is showing up and refusing to open the program. I've fixed it before, I just don't remember how. Please help! Image linked: https://gyazo.com/04414468e2f3600a63ed05db21d65d2c
