Is it to late for me to do the same?

I just found out that the college I transferred from got sued for taking money from students. It was a private college. I had two scholarships (not from the school) that cover and was over my whole tuition and was told that I had to take out student loans. I also had to do work-study. One semester I couldn’t because they said I had too much money to qualify for work-study. Also students stayed in financial aid office. I asked them where student loans money went; they will say we sent it back. Most school will have you sign a paper that says you want to return the money. I never got anything back from this school. (Both scholarships allowed you to get the left over amount back). So I transferred to another school. I never had any problem with financial aid at this school. I get my money back. Now that I’m graduating next year, I will have to start paying back the loans. I look over my loan statements and I found out they didn’t sent any of my money back. The school statements said they did. Would it be too late for me to file my own lawsuit against them?
