Hi Rasweig,
You should connect direct to the Dante card Primary port. Assuming the Dante card has the default network settings (zero-conf / DHCP), your computer should be set to DHCP (not to a static IP address).
Can you see the card in Dante Controller? If so, double click on the device to open its properties and check the firmware version. Depending on the firmware version, you might need a different version of the Updater tool, as explained on our website:

If you are upgrading your M-Dante Module Firmware from version 3.4.15, you will need to upgrade to V3.6.4 with Dante Firmware Update Manager V1.3.2 first, then install the latest Dante Firmware Update Manager V1.4.5.7 and upgrade the module to V3.7.0.
Note that the old Update Manager might have an expired certificate – if the Mac doesn’t launch it, try rolling back your system date to late 2012.
Hope this helps.
