To be clear, as it seemed to elude some of the folks above, Chordie's songbook is on the My Songbook tab at the top of the Chordie web site. Chordie does not produce and is not liable for third party apps that claim to be Chordie friendly. It's a shame the fellow above lost his songbook, but he got several suggestions of what to use to re-export the songs from his Chordie songbook.
I think it's important to take this opportunity to make the tangentially related note that Chordie hosts precisely NONE of the songs. Chordie allows songs hosted elsewhere to be edited, modified, and saved to a songbook ON THIS PAGE. We do not, to the best of my knowledge, sponsor or promote any Apple or Android app for exporting songbooks to tablets for later viewing.
