It seems SecuRom is detecting windows XP being Virtually installed and thinks your pirating the game.
From the wiki:
SoftICE is a kernel mode debugger for Microsoft Windows. Crucially, it is designed to run underneath Windows such that the operating system is unaware of its presence. Unlike an application debugger, SoftICE is capable of suspending all operations in Windows when instructed. For driver debugging this is critical due to how hardware is accessed and the kernel of the operating system functions. Because of its low-level capabilities, SoftICE is also popular as a software cracking tool.
My guess is this is used in a virtual installation of Windows and SecuRom won't allow the game to be played in this environment as it is used to pirate software.
As for playing the game in a 24 hour period... not going to happen it is too huge to get done in a day.
Best bet is to reinstall windows XP from scratch with SP3 re-installed. The problem with that is reinstalling all your stuff and backing up all files. He's a grueling few hour project.
