Problems with incomplete worksheet.

I have saved a .mw worksheet, which i cannot open in Maple, and i get an error code:
"There were problems during the loading process. Your worksheet may be incomplete"

I have attached a link, where a user is helped with the same problem, but i cannot understand the solution there has been given:
