ok, here is the update on my problems, yes I definitely had the right cards, but could not enter, I emailed support, they entered me manually. In the tournament I immediately tried to rebuy (I had 3 extra cards), got to the small screen that has a small box on the bottom to click for rebuy, could not click on it, it was greyed out, I clicked everywhere I could, and hit enter a lot, nothing. So I emailed support about that, they said they could not do the rebuy manually, but to reload the client and try again.
Well by then I had over 5000 chips and could not try again, tho I did do the reload. My next opportunity came at add on, I could not, again the grey box on bottom that would not accept my click. By then I was at 7000 chips, and did manage to finish in the "money", 2nd I think. I emailed support that I was unable to rebuy after the reload. They replied that they were sorry and if I needed any more help let them know lol.
Today I will try to uninstall and reinstall and then enter another of the tournaments just to see if it works. i definitely have the correct cards, support even verified that, could be I am doing something wrong, but I am following directions. It can't be that hard. I am only nominally stupid. Anyway, thanks for helping me dooley, if the last tournament doesn't require rebuys I should be ok.
