Harry, I hate to tell you this, but it sounds like your library is corrupted. You can try copying all of the records in it to a new table and giving the new table a vcx extension. Or, if you can open the library in the class browser, try copying all of the classes to another library. Otherwise, I'm not sure what you can do.
