So I receive this error : "Welcome back! It's been a while since your last log in.Please log into the RedFox website to verify your account!" I did that, but the error is still appearing.
Try unlocking your account through here : https://playredfox.com/users/unlock/new Check your e-mail address whether it is required to complete the unlocking process. If you have done the above steps and your account is still not working, please submit a ticket to the help desk under the "Technical" or "Account" category.
They will get back to you as soon as possible. Looks like you are a returning player as well, welcome back!
