I'm using Calibre 1.1.0 (32-bit) on a Win8 PC (64-bit). I just tried to convert a 31 MB MOBI file to EPUB, but the conversion failed. The input MOBI is in Kindle DX format, the EPUB output is iPad 3 format. I have attached a txt file of the error details. I see MemoryError a couple of times, but I don't know what it means. Please advise me on how to proceed.
BTW, after this conversion failed, I successfully converted another MOBI file into EPUB.
This is my first post to this forum. Thanks very much.
