For some time  I've been using Aurora on multiple machines, basing it on a thumbdrive.  I havent really had a lot of problems, very occasionally I lose a game because the Stevefire.mdb gets corrupted if it happens to be writing to it when I pull the memory stick out (I just need tp remember to shut down Aurora before removing the stick!)

That is indeed a difference the new machine doesn't have it installed yet.  (I spent yesterday looking for the disk which for some reason wasn't in that box of disks and manuals I'm sure everybody has)

Will report back when I get a chance to try it post install.

I'm having an interesting problem at the moment trying to migrate the game from one computer to another.

Both machines are running 5. 2 without problems.  The new machine can start a new game and the old machine can continue with my old campaign as normal.

Transferring the database from the old machine to the new results in Errors 3265, 3061 and then a long string of 91 which matches closely the description of what happens if you muddle the installation process.

Transferring the whole game folder from old to new results in the same behavior, not functioning with the database that was copied along with the game but working fine if I use the database that comes with the 5. 2 patch.

So I'm left thinking that there must be some difference in the windows environment that allows the game to function normally on both machines but destroys database compatibility, I can't however think how I might figure out what that difference is.

If anybody has any thoughts I'd appreciate the input.
