Encountered validation conflict

This is the first time I encountered this so my assumption is that by editing the uses_Registration.php page, I must have applied a new extension that is conflicting. I can't find anything in the support source about this, so it's my best guess.

It's the validation of the form. The User Registration Solution includes validation created by the WA Validation Tool Kit, I think.
I don't have that installed, or the CSS form building installed. But I do have the Form Toolkit and SecurityAssist installed.

In my Server Behavior panel, I have a behavior for validation called "WA Server Validations". Anyway, I clicked on that and removed the UserCountry validation after I removed the country text field. I think that added the conflicting include file.

So now I have two includes and I don't which one to remove. Or if I should change the whole form to match the new one.

I have both;

require_once("../WA_ValidationToolkit/WAVT_ValidatedForm_PHP.php");
require_once("../webassist/form_validations/wavt_validatedform_php.php");

Thanks,
