Bought a new copy of Civilization IV, but continue to receive message application quit unexpectedly when attempting to launch. Running 10.5.2 on new dual quad-core mac pro with NVIDIA 8800GT and 4 gigs ram. Have been exchanging emails with Aspyr tech support without luck, and they continue to say it should run fine. Things suggested and tried: 1. Successfully patched - 1.74 2. Attempted Open with Rosetta 3. Verified HD format non-case specific 4. Reinstall: drag and drop into application folder Any other ideas?
