__init__() takes exactly 1 argument (2 given), what went wrong?

It's basically a signup form for a site I'm working and its also not working too, but my main problem right now is the __init__ error. Can you check what and where it went wrong?

views.py:

from django.views.generic.edit import FormView
from django.views.decorators.csrf import csrf_protect
from django.core.context_processors import csrf
from django.contrib import auth
from authactions import forms
from authactions.forms import CreateForm

class SignupView(FormView):
    template_name = 'authactions/register.html'
    form_class = forms.CreateForm

def form_valid(self, form):
    profile = form.saveUser()
    user = authenticate(username=profile.user.username ,password=profile.user.password)
    auth.login(self.request,user)
    return HttpResponseRedirect('/profiles/')

forms.py:

from django import forms
from profiles.models import UserProfile
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm

class CreateForm(UserCreationForm):
    username = forms.CharField(required=True)
    password = forms.CharField(widget=forms.PasswordInput())
    password2 = forms.CharField(widget=forms.PasswordInput())
    email = forms.EmailField(required=True)

class Meta:
    model = UserProfile
    fields = ("username", "password", "password2", "email")

def saveUser(self):
    user = super(UserCreationForm, self).save()
    user.username = self.cleaned_data['username']
    user.password = self.cleaned_data['password']
    user.password2 = self.cleaned_data['password2']
    user.email = self.cleaned_data['email']
    if user.password != user.password2:
        raise forms.ValidationError("Mismatched password!")
    user.save()
    return user

class LoginForm(forms.Form):
    username = forms.CharField(required=True)
    password = forms.CharField(widget=forms.PasswordInput())

html:

<!DOCTYPE html>
<html>
<body>
        <div id = "signup_form">
            <form action="" method="POST">
            {% csrf_token %}
            {% if form.non_field_errors %}
                <ul>
                    {{ form.non_field_errors.as_ul }}
                </ul>
            {% endif %}
                <table>
                    <tr>
                        <td>
                            <h3>Personal Info</h3>
                        <input type = "text" name = "username" id = "username" class = "field" placeholder = "Username" required /><br />
                        <input type = "email" name = "email" id = "email" class = "field" placeholder = "Email" required />
                        <br />
                        <input type = "password" name = "password1" id = "password" class = "field" placeholder = "Password" required onkeyup = "check_length(1)"/><br />
                        <span>Password must be at least 7 characters long.</span><br />
                        <input type = "password" name = "password2" id = "password2" class = "field" placeholder = "Retype Password" required onkeyup = "check_password(1)" />
                    </td>
                </table>
                <input type = "submit" value = "Sign Up" id = "button" />
            </form>
        </div>
    </body>
</html>

You don't show your urls.py, but the problem is probably there: you need to use as_view when mapping a class based view:

url('^register/$', SignupView.as_view(), name='register')

I can't tell if it is the copy-paste or whether your code actually looks like that, but the class Meta has to be indented within your CreateForm class. In fact, the saveUser method has to be indented as well.
