SecuritySuite - Enhanced SuiteCRM Teams

I have installed this plugin on SuiteCRM 7.5.3. After the install finishes I am asked for the license key. I enter a license key and click "Validate" and nothing happens. It just say Validating and then nothing. There is no continue button. Below is what I found in the log files.
