technical problem with certification

There seems to be some problem with the certification.
I try to do the module 13 certification in rocket french and get this message after the first few:

Hi ArminZ,

I’m really sorry to hear that! If you could drop us an email at support@rocketlanguages.com with an example of a phrase from the test that gave you trouble, that would be fantastic. 

We look forward to hearing from you soon!

Hello Indy,

that problem somehow resolved itself - no idea how
I could just do the module 13 certification without a problem.

Hi ArminZ,

Thank you for letting me know; that's good to hear!

I will ask our IT team to look into what happened here nonetheless.

If it pops up again, please don't hesitate to get in touch. 

All the best!

Indy
