I'm not sure if this is reported yet, but I'm unable to load the xml created with the new version of articy draft, I tried 2 artict projects and the result is the same (the only error message I get from DS is:
I'll have a patch for this by tomorrow. Early in the articy:draft 3.x releases I reported a bug with their XML format with string variables. Nevigo just fixed it in 3.1.8 by updating the XML schema. The Dialogue System just needs to be updated with the new XML schema.
Patch 1.7.6_20171211 was released on the customer download site yesterday. I just PM'ed you your access info. If anyone else needs access, please PM or email tony (at) pixelcrushers.com with your Unity Asset Store invoice number.
If you notice any issues, please let me know. This is a patch version. Some more updates to the articy converter are scheduled to go into the full 1.7.7 release.
