I do the same from a dropbox folder. Just install aurora to the dropbox folder and it automatically syncs. Just make sure you got your windows files set up on both machines.
I'm currently playing on my desktop when at home, and on my laptop when abroad. You just need to have the same installation on both, and then copy the database Stevefire. mdb from one to the other. That's all.
Stevefire.mdb is the only file you need to move. Just make sure that if you have made any alterations to your flags/race images/planet images files that they are copied over to both computers.
