The 2.0.6 version of each theme is now available and patches this issue up! Just download it from ThemeForest (at your Downloads page), then deactivate your old version and install/activate the newest one.
1. Manually add the OptionTree plugin (Plugins > Add New > Search for "OptionTree") - this will automatically update the theme options plugin to the latest version in the case that the theme-update doesn't do it automatically.
2. Update all of your other plugins. It's possible that there's another plugin that you are using that's causing the issue.
3. Turn off any page caches that you might have running - they might hide any fixes that the above steps perform as it'll save the broken version of the page. As usual, if this doesn't fix the issue, deactivate your other plugins to determine if one of them might be causing the conflict with the new WP 3.5 dashboard scripts.
You might run into a number of other issues when upgrading to WP 3.5 that are unrelated to your theme; View the full list of 3.5 troubleshooting tips and the list of known incompatible plugins here: http://wordpress.org/support/topic/troubleshooting-wordpress-35-master-list Happy Updating!
