Issues with Certifications

Hello everyone,

I've purchased the 3DEXPERIENCE CATIA for Students which supposedly provides 3 certifications. Upon trying to complete the certifications, the ENOVIA Collaborative Business & Industry Innovator shows that the content is not accessible, whereas the CATIA 3D Innovator does not have credits. Finally, the CATIA Mechanical Designer simply is a white screen. 

It is very frustrating to pay for a service, but not being able to take advantage of the features listed in that service. 

Thank you in advance.
