My form is enabled in the preferences but it is still disabled?

I enabled it in the preferences

I checked your account and I didn't see any guilty fields. Please keep in mind that asking for login information such as username and password can lead into your account being suspended. To avoid it, please read our terms of use. 

I have now activated your account so you can use your forms properly. 

Hope that helps. If you have any questions, please let us know. Thank you.
