Suspended Account: Form not found error

I keep getting Form not found error when I try to preview my form. This started happening recently. So now the forms that used to work on my site is also not working. I tried deleting and recreating the form - no success yet.

Please help.

Thanks

Thank you for contacting us.

Let me please inform you that we do not allow password fields. It appears that one of your forms was considered as suspicious by our anti-phishing filter, so that your account was automatically suspended.

We can re-activate your account if you are fine with removing the password fields.
