I am also having this issue too. it hangs for hours, I wonder if a hot patch needs to be figured out and released to fix this issue. I have been trying to update since the release of the The Cloaked Ascendency went live. The launcher is only showing Patching and seems to be hung up on that, it I don't know if it is stuck…
I have played Neverwinter during the Beta test, and I see on my Arc Profile says that I have played Neverwinter for None, as if I have never played it. What is the matter?
