@Legionaire: try copying the entire stack trace (the entire content of the scrollable text) and posting it. Those kind of stack traces are very useful to the people who write the software, but only if they get the full thing (and not a cut-off snapshot).

Incidentally the error boils down to a flaw in the source code, because the program tries to read "beyond" the end of the file; alternatively if the software is to be taken as the absolute and definitive yardstick the file must be corrupted for it is apparently a few bytes short...

Disclaimer: I did not write that piece of software, so I can't give you any help with it.
