Some of the ebooks players have will automatically lock. This is because the supplier of the ebook service no longer exists. For now I'm using another ebook service, but I hate relying on another company so I'm having my own ebook software created. The programmers already started a few weeks ago, and are a few weeks from completion.
Besides the roulette computer and online wheel analysis software instructions, the ebooks are only introductory documents anyway so the delay is not critical. Where ebooks need to be available promptly, ie to new system players, for now I will use the temporary ebook service.
