After I bought the software, I started to operate according to the instructions. When my ea transaction was opened, the dll was also opened. A computer showed that it could not connect to the server. I changed to another computer. When I entered the activation code and clicked to activate, nothing happened. Come out the main interface. I do not know why. I have sent emails many times, but no one helped me solve this problem, and the software I bought was useless. I am sad.
