Unable to access information from developers corner

Hi,
My apologies if this is not the right forum. I registered with the Developers Corner after reading a blog at diydrones that Invensens was allowing the use of it's code for OpenSource use. I am planning on using a MPU-9150 for an opensource camera stabilization gimbal, and registered with my hotmail account. Yet, when I try downloading the Embedded MotionDriver or MotionFit Wireless SDK, I get the following message "current registration status does not permit access to this file. If you have any questions or would like to re-validate your account by registering with your corporate email address, please fill out the form provided on the support page."
Does everyone have to register using a corporate email address?
Thanks for your help.
