I too have raised it to support and here for the same issue, no help there. Tried different browsers, uninstalled and reinstalled, tried VPN or without. Loading TT Premier on different computer says key is nit valid despite showing it as a choice for active key and 1 of 5 allowed installation. Its definitely a TT issue and their QA/Engineering needs to resolve . Its been weeks or give money back or provide another key to try
