Hello Daniel,
we can certainly give you support 🙂 It is easier to get in touch with us over in the UE4 forum, if you didn’t do this already.
Though emotiv is constantly changing their software concepts and policies, the concrete API connection shouldn’t have changed that much – so we should get it running.

PS: For Raw Data Acquisition – since emotiv has changed to a subscription model and possibly some kind of cloud-based license identification, we are not sure that future Research / Advanced SDKs or furthermore locked-down Headsets MIGHT not be able to connect to Openvibe through its provided driver (our favourite way to capture Raw EEG). Please keep in mind that we do not know in how far current emotiv policies allow standalone hardware compatibility with Openvibe or Neuromore to send your own processing and algorithms to UE4.
