WARNING: After you've synchronized your trading environment with your MQL5 VPS, you DO NOT NEED TO CLICK THE AUTO TRADING BUTTON AGAIN in your local MT4/5 terminal, because if you do, you will trade with your Expert Advisor twice and that is very dangerous!

My MT4 is showing MQL5 account with VPS subscription logged in, but MT4 was dropped out from VPS. When clicking on VPS, it asked me to subscribe. How should I fix this? Thanks!
