You could try moving the data files:

/Users/<your user name>/Library/Application Support/Sighthound Video/ and stick it in
C:\Users\<your user name>\AppData\Local\Sighthound Video\ (edit: I think I got those reversed for your use case, but you get the idea).
I doubt this will work, I'm not looking at whats in those directories right now, but if it's just plain text XML files or something, you might have a chance.
