Our hosting provider experienced massive problems with their server hardware. As result our web and license server are currently not available.
To restore all services will take a considerable amount of time but we are working on a solution that all clients can use their purchased trading software as quickly as possible.
Regarding this matter, we will contact all clients within the next 1-2 business days.
We apologize for any inconvenience this may cause and want to thank you in advance for your understanding.
