The error message was something along the lines of "invalid file, file doesn't exist" & it mentioned lines 50 & 52.
I was sending the auto-save file when getting the errors. I then reloaded the auto-save, saved the game, and then when I sent the compressed file, it worked fine.
I was trying to email it in, but as I stated above, not everyone can see your email. You may want to do something like:
'If you have an error, please email it to 'errors@gotm.com' or click the link [here].'
Hope this helps.
