Opened an account on Arvixe.com, deleted concrete5 version 5.7, installed c5 version 5.6.3. Now I'm unable to connect my site to the c5 community. I keep getting a CAPTCHA that tells me to enter confirmation code after solving challenge above, but there's no challenge or CAPTCHA image on the pop up. When I enter my username and password, I get an error message "You must specify a site name" and "Your site token must be 64 characters" and I am unable to sign in to my concrete5.org account. I've deleted 5.7 from previous sites and installed version 5.6.3.3 with no problems in the past. Any help is appreciated.
