In order to gain access to Tapatalk, you need to be registered on the site for at least 2 weeks and have a minimum of 10 posts. We have this system in place to prevent people from posting spam all over the site.
MedCat, it looks like you have only been registered for 5 days. I have gone ahead and changed your account so that you have access to Tapatalk now. Please let me know if it works.
Saske Khan, you have been registered long enough and am not sure why you are still not able to login. Please go into Tapatalk settings and try to clear your cache in the Tapatalk application and then try logging in again.
