Should I apply for this job again?

I applied for a job at a store a couple of months ago as a courtesy clerk, so id be pushing carts, and stuff like that. They emailed me, and said they went with another applicant. I have a friend who works there, and told her this. She talked to the hiring manager, Because she knew they are still looking for someone. She said that the hiring manager said to apply again, but make sure I fill out, and give them all the information they ask for. Maybe I didn't? But when I applied, a page popped up, and said "thank you for submitting your application". I don't know why it would even let me get to that point if I didn't fill everything out

Should I apply for this job again?
