Thank you both so much for replying. Nevermind! I finally figured out my error!!

I would appreciate anyone's help right now. I have downloaded files that are compressed RAR files but i cannot open them. I have followed the instructions on this website. Downloaded both WinRAR and Powerarchiver and neither will work for me. It is upsetting since I am only able to download due to my donation. Please let me know if I am doing something wrong or if there is a better way to open my downloads. Thanks!
