two hours? log out and try again.
Try a different browser if it is not responding.

Something in your browser (or browser add-ons) could be blocking the Captcha, or you may not have allowed cookies.    I left several things to try below.

But there is no reason to wait on it that unusual amount of time.  If the pictures don't appear within seconds, it's not going to happen until something is fixed in that browser, or you try a different one.

If the "I am not a robot" Captcha is not working right or has missing elements, try this:

NOTE:   Are you using any ad blockers or script blockers?   If so, that may be blocking the Captcha.

Otherwise, here's how to troubleshoot:

• First, simply refresh the page in your browser and see if that changes anything.
  
• If not, then log out and clear your browser Internet cache.
• Close the browser and reopen it.
• Make sure cookies are allowed/enabled in your browser settings so the Captcha will appear.
• Log in and try again.
• If still unsuccessful, do all the above, then this time open a private window/private browsing (aka "incognito mode").
• Log in with the private window (again making sure cookies are allowed) and try the efile again.
  

Or see if trying a different browser (with cookies allowed) will solve it.
