There is a known bug in Voxie 1.5.1 (but not in versions later than that) that if you use special characters in the name of the file (such as / or ?), you may not be able to later retrieve the file. So you should not name a file "My File 1/3/09" as the slashes will trigger this bug. We have fixed this in Voxie 2.0 and higher which was submitted to Apple on 1/26/09 but needs to be approved by them. We would have warned our customers but we have no way of contacting our customers until they contact us. We apologize for any inconvenience this may cause you.
