I see that I can buy bonus spin on WOF by my RP, so I bought 1 bonus spin on WOF for every free roll, but when I go to spin the wheel, I see that the client seed section is FROZEN and I can't change it.
Then I refresh the page to see if the client seed is change and the system not allowed me to spin the wheel and erase my bonus for this roll.
SO WTF?!
I followed your way to change the client seed you mentioned on the freebitco.in thread just a few minutes ago.
I was able to change the client seed successfully so I think it must be a technical error for the time being.
May be you can try again for a new spin tomorrow and it would work this time

Also, I think you would have missed a requirement for the no captcha for free roll.
You had 0 satoshis as per the video whereas you have to hold the amount for the free roll.
This applies to free spin from email or from bonus spin when you bought it from yours RP?
Also I told that I bought the tickets to unlock the captcha again, because I was unlock it before.
