Telerik Rad Captcha - Validation always returns false - ASP.NET

Question

I have tried to use a Rad Captcha control in my ASP.NET application. The control will display the images, but I can never get it to validate. No matter what I do it returns false.

I am using the current Telerik tools: UI for ASP.NET AJAX Q3 2013 SP1

I have an ASP.NET button, in the click event I have this code here:

RadCap.Validate();
Page.Validate();

if (RadCap.IsValid)
{                
    Label1.Text = "Right";
}
else
{
    Label1.Text = "Wrong";
}

I also have tried to add a validation summary to the web form, and setting the validation group to the same name on all the controls. Can some please tell me what I am doing wrong?

Answer 1

I had a timer that was controlling my ad rotator, if I disabled the time, the Rad Captcha works fine.
