iBooks preview not working?

I recently converted one of my books into an iBooks format using Author. However when I connected to my iPad and went into 'preview', I saw my device, clicked it, but the 'preview' button to enable the previewing process was faded and I could not click it. Has anyone actually used the preview feature enough to give me some help? Thanks!

Solution 1:

Had the same issue with my iMac running Lion and iPad 1. The iPad was visible but greyed out, as was the preview button.

Here's what worked for me:

• Connect iPad to Mac
• Open iBooks on iPad
• Click on preview in Author
• Close iBooks on iPad
• Cancel preview and tap on preview again
• Open iBooks on iPad again

Not sure why or how, but it worked for me.

Good luck!
