Please email supportdos@larian.com, with a description of the problem (or link to this topic), your latest save and maybe the most recent working save and oldest that crashes. You would need to transfer them to a USB flash drive first.
In the Saved Data in System Storage section of the Settings menu, click Copy to USB Storage Device, select the relevant save(s) and Copy. From there you can optionally zip the save(s), then copy to email or upload to Dropbox or Google drive, etc, and provide a link.
