Request Code Invalid

Hello, I am having this weird error where it says that my request code is invalid (error 3)


I've tried both the standalone activation and the activation and both say that the code is invalid.


I've also tried resetting the request code 3 times. 3 different invalid codes.


I've emailed trying to get an activation that way and they reply saying that the request code is invalid. 


Any instant help on this, I'm reluctant to phone, or email anymore people (due to the slowness of their replies.)

Your activation code must match the one created by the request code. If you reset it, your activation code won't work. Do not attempt to type in your activation code. Copy the entire code and paste it into the box.

Your online activation request has returned an error (400) which is not allowing your request to be processed using our automated systems.

Click the "Use another method" link below to complete the necessary forms and submit your request to the local Autodesk Business Center for your area. A Customer Service Representative will respond within the next 2 business days.
