Essentials got confused
I think I did something wrong. I registered Essentials with "register new product" which then threw some kind of database error. Then I authorized the key (Balance) and Essentials seems to be registered ok also. However when I start Essentials it requires authorization over internet. Authorizer programs says only I don't have "Rack Extensions" installed and that's it. Why me God? And what is "Rack Extensions"? And why this shit happens to me every time?
