You really should consider changing your CAPTCHA. It sucks!!!!! It is meant to keep bots out and not make humans miserable. There are lots of other fun CAPTCHA out there.

During registration, I had to try the five times because the CAPTCHA was wrong due to the fact that the image was blurry.

If not for the fact that the file I needed required me registering before I could get it, I would've left and the worst part, it isn't friendly on mobile.

Use ReCAPTCHA if it comes to it or try Visual CAPTCHA.

Your CAPTCHA sucks and it's not fun either!
