Hi - I posted this some time ago. Seeing if there is any new help. Muse on new computer opens, shows just a black screen where pages would normally show, then closes after about three seconds. I have to use my old computer to do anything on Muse. I have uninstalled then installed again on new computer. All other Adobe products work just fine - I have a CC monthly membership.
PC or Mac?
If PC, watch this:
From Adobe-Side nothing will, be changed or developed any further. So if solutions, provided earlier (realized your previous post) do not help, there will not be any help from Adobe.
I am aware that this not help really 😞 at all.
Try disconnecting from the Internet BEFORE you launch Muse.
Post back if you still need help.
