It seems that the loss of graphics referred to in my previous thread is just the tip of the iceberg. It now appears that I have lost not just the graphics update material but the entire update. But it doesn't end there. When I hit the Check for Update button to reinstall I get a " .. could not be downloaded. Please contact Matrix Games for help." message. Unsurprisingly when I then hit the Matrix website I can't find anywhere to report the issue.
What's going on, guys?
