When you installed, did you replace your existing version of Studio One? It is possible to have a co-install of different versions of Studio One. You must find where you installed and run the application from there, not a short cut, as it may be pointing to an older version that still exists on your computer. Also, by opening Studio One and going to the "Help" and "Check for updates" option, you can update from the software which may very well solve your issue.
