Title: Invalid License Error 538 on Crosshair MT5 and Top Clock MT5
Hello,
I migrated from a Dell Inspiron PC to a Dell Vostro 3710 PC.
I am using OANDA MT5 on Windows 11. My MQL5.community account is logged in correctly, but two Market indicators fail to load with error 538:
Crosshair MT5
Top Clock MT5
I have already reinstalled MT5 and tried installing the indicators again directly from the Market, but the problem persists.
The Journal shows:
loading of Crosshair MT5 ... failed [538]
loading of Top Clock MT5 ... failed [538]
Could you please help me resolve this invalid license issue?
Thank you.
