0x000001a0: This is maybe a problem with the harddisks, that maybe a sector on the HDD is damaged, and not a problem with MoO2.
You could try this:
Go to the command line (windows key + R, type in "cmd"), and then type there in "chkdsk c:/f" (c: is the letter of the harddisk. If you have installed civ on another one, d: for example, then change it), hit enter, type in Y. Then restart the computer, let the programm run, and try to start MoO2 again. Maybe re-install MoO2 after that.
