Adding the company and editing the datas

I have some issues when I added a company to crunchbase. When I finished the aditing of profile, there appeared 404 mistake and the  company isn't showed anywhere. Then I tried to edit another company and my edits didn't save.

Now I try to do some edits and there appears To start contributing, link your social network profile to your Crunchbase account. Our team will then review your account and enable it for contribution (this may take up to one business day). It appears again and again. But my profile is linked.

Dear support, how can I solve this issue? 

Thank you for the answer
