TrinityXero, if you have not already done so, please submit a support ticket so that we can assist you with this. Please go into the main TERA folder and run the program there called EMEdiag. When it has finished, please save the results and include that .txt file with your support ticket.

Also, please make sure to include in your ticket that you have already tried reinstalling from Steam as well as our site, so that we do not recommend you do that again.

Thanks!
