Frank,
I am having the exact same error. It does not matter for me whether I have the captcha enabled or not I get the same error even when I type the captcha in correctly. However I think that this is a Browswer specific issue because it only happens while in Google Chrome.
Error:
The code you entered incorrect.
The correct tekst was XXXXX while you typed XXXXX.
Try it again
In addition when will you make a release without using Flash since all the Apple Platforms (iPhone, iPad, etc) are no longer supporting it?
