problems opening files

[Steve_from_accounting]

whenI open one file I can edit it listen to and it works fine. but when I try to open a second file no materwhat file it is or even if I try to open a new file the screen flickers a little and then wavepad imedetly crashes. It does this every time exactly the same and it doesn't even generate an error message it just says, "wavepad has generated and errors and must close." and then it does. How do I make it stop doing this?
