Hi. Today I tried sending Huckleberry Finn and Tom Sawyer to the book port. I tried sending those books from the CD on a 128 meg flash card with the only file being Part I of the 9/11 Commission Report. I now am receiving the following error message: fs memory, out of drobj structures. Before this occurred I sent the files and thought they had been transferred to the book port. I disconnected the unit and heard book port 11 and then the unit locked up. I restored the defaults and now am hearing this error message. Please, tell me what has caused this and how do I resolve it in the future? I will remove the batteries and start from scratch. Thanks. Michael Massey
