Ganglion, I suggest double-checking to make sure that your graphics drivers and interface systems are fully up to date. Although I haven't seen this with Calibre, I have seen it with other programs, and about half the time the problem was that the program wanted/required a more-recent graphics driver (for the hardware) or interface (like DirectX) than was installed on the machine. Those gave similar "won't start up" behavior, and were fixed each time by manually updating the system-level graphics stuff.
