Thank you for your respond and the verification.

We kindly ask you to use a normal internet access, which means no proxy & no ghost-walk tool, to login to your TERA account. Then it will be working properly again.

In this regard we would like to refer to point 5.4.6. of our 'Terms of Services' where it states:

"The use of the TERA platform by means of an anonymisation service or similar measures that are suitable to hide or conceal the true IP address and/or the identity of the user is not permitted."

You can find our 'Terms of Services' by clicking to the following link: http://tera-europe.com/terms-of-service.html

If you have any further questions, do not hesitate to contact us again.

Best Regards,
