Hi Alex,
You don't need to use an external program like Dx-Telnet to receive spots. Use the integrated Telnet support which is very easy to configure:
Please read the Quick Start and Setup guide here:

It's explained in "Setup a DX Cluster Telnet server connection to receive DX spots". You will see is very easy! The integrated Telnet support of Swisslog offers many possibilities so you don't need DX-Telnet at all. I recall I configured it years ago and worked as explained. Probably now you will need to add exceptions to your antivirus and firewall to DX-Telnet as well to avoid it's blocking the communication. But I recommend you to use the Integrated Telnet support.
