We need more details. First question that occurs to me is: Are you running Steam in "off-line" mode? 2: Are you seeing any error messages? What do they say? 3: What (if any) other mods are you running? 4: Which version of LW are you running? 5. Which game options (Training Roulette, Red Fog, etc.) did you select? Please review the LW troubleshooting steps (included in the download). -Dubious- 1. Yes offline 2. Mac crash logs. 3. No other mods 4. The latest b15d 5. I think Strict Screening, and a few other options Yes, I've gone through the documents, and I find that if I delete the profile.bin I'm able to start the game, I do get a series of prompts about ambiguous file names in the Voice files directory (I'll attach the screenshot if I figure how to do it) but I'm able to start successfully successfully nevertheless. The moment I complete the first mission and click on the "Continue" button, the game crashes to desktop. Do you want me to attached the logs?
