@drwtsn32 is correct that the green progress bar (and the “x” icon to the right) mean something is still running.
When nothing is running the progress bar should have a white background and no “x” icon on the right, like this.
Your screenshot shows that you’re running a beta version so it’s likely either 2.0.2.1 or 2.0.3.3. If it’s 2.0.2.1, then you’re probably running into the issue mentioned here where a database “vacuum” command step is started AFTER the “Finished!” message is displayed.
If you just wait until the green background goes white, then the “Run now” link should work as expected. Though you’re probably better off updating to 2.0.3.3.
Of course if you’re already on 2.0.3.3, please let us know because that means either the issue came back or a new one has cropped up.
