How are you trying to connect? Is it the hog driver or CITP?
In the meanwhile I hope you are aware that we offer a paid upgrade to the current product version. It is still available for Capture Argo to upgrade to Capture 2020 without having to pay for the upgrades skipped in between. By the way once we release Capture 2021 next year you will no longer be able to upgrade to Capture 2021 or future product versions, and also there will be no further library updates. This is all described in our license policies. Looking forward to your response.
