New V2 Firmware not as stable / freezing in record

Hi,

OS version?
Do you have KB3123479 installed?

Please remove the current driver then reboot the PC and install the 6.19 driver on your PC.

Note: Windows requires a new extended validation code signing(based on SHA-256) mechanism for drivers. Earlier versions of Windows 7 and Windows 8 cannot verify the new certificate, in which case please update your windows with the hotfix KB3123479.
