I just installed both versions of the shaper on my testing server without any issues, even after doing a full update of everything. Unfortunately, without a way to look at the site you are having issues on, there's not much I can do.
The fact that you had no issues with the theme on your main server would suggest that it may be related to your local install. Have you tried installing the shaper in a separate location on your web host?
Also, have you installed the Vertex Upgrade Patch
? If there have been any changes to WP since the release of the theme/shaper which would cause conflicts with the framework, the patch will have a fix for that. The download for the patch is updated any time there are any changes made to the framework, especially compatibility fixes.
