The Driver was installed from your original Website (epiphan.com) and with the following error message:
German Version:

Bei einer vor Kurzem durchgeführten Änderung an Hardware oder Software wurde möglicherweise eine Datei installiert, die falsch signiert oder beschädigt ist. Möglicherweise handelt es sich auch um schädliche Software einer unbekannten Quelle. (Code 52)

I have tried another Frame Grabber and it happend the same, I have tried in other USB ports, I checked my cable Connections.
I experienced the same issue, went back to the previous version linked by @AdamFrame and now it works.
Why doesn’t the newer version works though? I guess some improvements & fixes (such as the resolution to pixel shift can be found only in the latest driver). When will the newer version work on Win10?
You mean the newer version by @AdamFrame did not worked? And you went back to another version?
For me the version mentioned in the Link worked perfect and it is also stable considering my environment. Also, I must mention you have to complete uninstall one version before installing another version and also disconnect the device from PC.
The 3.30.7.8 version has a signature issue with some Windows 10 systems, specifically relating to secure boot. We are just waiting for a new signing from Microsoft to put up a new version. If you really want to use the 3.30.7.8 version you can if you disable secure boot on your mainboard bios. However I would just recommend using the 3.30.2.10 drivers for now.
