I have an .indd file that is 125 pages long with a front and back cover. When I first created the indd file and tried to export to just an epub, it stopped working. The export progress bars looks to be about 15% complete with the last thing processessing is a .png file. I then saved it as an idml file and created an export to Kindle. That went fine and it produced the mobi content. However, when I go to export to an epub, it hangs up in both the .indd and the .idml files. The export to Kindle seems to work just fine from both. Any suggestions? By the way, there are no error codes.
