There's a corrupted file within your limewire, the thing is can you remember what you last downloaded before the error message started to show up...
Usually it's a movie file that causes this to happen...
You will also find that you will not be able to access your shared folder outside of limewire either...
If you can remember the file name delete it from your LW library, if you cant keep LW open for long enough use your comps search and when it finds it delete it from there...
