when users try to post comments they are getting the following:

Sorry, the following error occurred while processing your comment:

Value cannot be null.

Parameter name: Challenge


this even when all fields are correctly filled.

any solutions?

"Challenge" parameter usually injected by extension like Recaptcha. Try to disable Recaptcha and see if error goes away.

That fixed it, ...

so now how do I get a CAPTCHA setup that will work with the comments and slow down the spammers?

This guide is for BE1.6.1, new UI a little different but process should be the same.
