I have created a trial helpdesk with one of my company email accounts and invited myself as an administrator. But every time I try to login to the .eu helpdesk, I'm redirected to the .com site. I though I made a mistake and set up a trial helpdesk there as well, but still want to login to the .eu site.

So, how can I 

- delete the helpdesk site I created on the .com entity?

- login with my account to the .eu helpdesk I was invited to?

Thanks for your answer
