Im having a commun error 0x8007000d pointing to my web.config file saying that my configuration data is invalid, Im trying solve it for hours and after look a lot of solutions in google  and I still didn't solve nothing, I saw a lot of people with similar web.config so I dont know why it dont work for me. I´m using asp 5 and beta 8
