I edited the file and emailed it back.
If you are so inclined, you can check out the file in a hex editor, to see if you can spot what you were doing wrong. Since your characters have 264723 experience points you can search for the reversed hex value of that, '13 0A 04 00'. There will be 4 instances of this string (2 per character); the third one is just above the 'Base' term as described in the
hex editing topic. After the experience points, there are four more bytes (though unlike the example not all zeros), after which is the 3 byte value of your hero's skill points. I edited the first 2 bytes from '00 00' to 'F4 01' (ie the reversed hex value of 500).
