You should be able to see the group "Exhibition" (also if you are a sponsor or media partner) now when you click on "MyAccount" (you need to be logged in!):

On the MyAccount page you can see directly above the groups section a new link called "Create your Company Profile". Please click on it to create your company profile. You will find the product finder keys at the end of the company profile submission form.

Please follow the onscreen instructions there and click "submit" to submit your profile.
