I've been member for several years also.  I tried the two codes you did, but none of them work.  I received the same answer as everyone else.  Only invited players will get that bonus.

I downloaded the casino and couldn't get the bonuses. Same message invalid code. Oh well.

i believe the problem with this is the download link that the bonus is on.  like myself, i think people downloaded the link that does not allow you to redeem the coupon. if the casino says the coupon is only for those who got the e-mail, simple solution is to post the link from the e-mail or some one (who was able to redeem) can help by posting the link to download that they used. thank you in advance to whomever that will post the link.

Jim I went through the same link you did and I was unable to get the bonus.

I know that, many of us here did Deb, I truly believe that what occurred was they decided to throw the freebie out there to test the new software and were unprepared for the flood that responded. The first 200 or so were able to use it, no problems... and even follow through with the second code, but after that as people began querying and harrying the live support a "field decision was made to modify the offer to 25. They tried to go with it for a bit,, look at the time stamps on this thread.
There is a big lull where no one is getting the codes and suddenly the new code was being accepted and the pop up suddenly appeared claiming "invitation only".  Even that did not stem the flow as the ball was already rolling and the codes were available on at least three boards ... stop and think... LCB had 1700 views that morning.  Then around  3:00 ET it was over...
