Hi, James.
The VoiceAttack.dat file is saved in the app data folder of the current user of your pc. The first versions of VoiceAttack saved in a single location (installation folder), but, I found out very quickly that users wanted to be able to use VoiceAttack with more than one user account. I changed VoiceAttack's structure (a whole lot), so, there's no going back. Sorry, bud :( The best I can suggest is manually copying the .dat file, or, if possible, add the user account folder to your drop box.
