I don't really understand how the server works with transferring data and stuff, but I'm supposing that the inventory data is kept in a file in the SMBO folder on your computer. It's possible that there's something strange with your internet settings that makes it hard for the server to connect with this file. Anyways, I really don't know much about this, especially since it's never happened before. Best is to ask Kimi or Hydra for help, but for some reason Kimi hasn't been on in over a week, which is really strange. Maybe he's preparing for his final exams or something. Sorry I couldn't be of any more help
