"Look, here's what happened. Please don't hate us!"
CCP has posted an official response to the whole Boot.ini fiasco, where players who patched their EVE client right away were having a critical file on their computer deleted that would cause the system to not boot up once restarted.
My name is Dr. Erlendur S. Thorsteinsson and I have been directing the EVE Online Software Group for the better part of this year. From my previous work experiences in the antivirus industry and following CCP for quite some time now, I have come to appreciate the need for full disclosure when things don't go according to plan.
Shortly after releasing EVE Online: Trinity at 22:04 GMT on Wednesday, 5 December, we started receiving reports that the Classic to Premium graphics content upgrade was causing problems to players by deleting the file C:\boot.ini, which is a Windows system startup file. In some cases the computer was not able to recover on the next startup and would not start until the file had been fixed. In this dev blog I want to tell you how this happened.
