I actually ran into a problem with having the closed / open beta client installed and then installing the steam beta. After steam finished installing it's STO beta, I tried getting rid of the one in the Cryptic Program Files Folder (renamed to be safe, then tried running the steam STO client). This made it think that I needed to re-download all 10GB. I put the Cryptic STO folder back and the Steam STO app stopped complaining. Now there were 2 installs, with duplicate .hogg files. I ended up using the Steam "Backup Game Files" on the Steam install of STO, then uninstalling the Cryptic install, then reinstalling the Steam version from the backup. That seems to have done the trick.
