I've seen lots of posts regarding Cakewalk hanging on "Creating UI". Thought I'd share what I found when it happened to me. I installed the current version of Cakewalk on my desktop computer. Installation went smooth, but when I tried to open a new project (using the 4-Track.cwt template), Cakewalk would hang on "Creating UI". I did all the stuff people suggested in other posts: uninstall / reinstall, disable anti-virus, run as Admin, don't install add-ons, etc - none of those worked for me
