Problem with MR816CSX after updating Kaspersky

Dear Steinbergers,

today i updated my Kaspersky Internet Security (KIS) from Version 2016 to 2017.
Since this update my MR816CSX ain’t working any more. If i try to open the control panel an error message pops up, saying “Failed to open control panel”. Trying to open the “MR Editor” brings the message “Cannot use Yamaha Steinberg FW driver”.

The interface disappeared from the device manager completely and i have the feeling that KIS2017 is somehow blocking my firewire port.

Does anybody have/had similar problems caused by Kaspersky?

Thanks for your help!
