Switched my STM32F4 discovery and now Virtual Com port is not working

i swapped my first STM32F407G-DISC1 discovery board for a new one and now the ST-Link onboard doesnt show up as a virtual com port in Windows 10 anymore. 


I flashed the St-Link with the new firmware, it runs V2.J30.S0 STM32 Debugger now.


I also installed the current Windows driver from here.


Now i read the DISCOVERY boards dont all have the virtual com, but in this site it says that my order code should have it (on my PCB is a silk print next to the USB connector that says "STM32F407G-DISC1).


Can it be that the silkscreen board code doesnt correspond to the "order code" which is mentioned on the above website?


Please help since i really need the virtual COM port.
