I received this error message in each of the 4 Blackwell games
Error message on startup:
Adventure Game Studio
"An internal error has occurred. Please not down the following information. If the problem persists, post the details on the AGS Technical Forum. (ACI version 3.21.1115)
Error: save_game: unable to open savegame file for writing"
AGS is trying to create the reset save game and fails. A possible reason is the file path; since save games are created within the user folder, a user name that contains special characters might cause problems.
You can also take a look at this:

Which Windows version are you using? Did you try running the game as Admin?
I am running Windows 7 as administrator.
What about other AGS games? Does this happen only for the Blackwell games, or is it a general problem?

I remember there was very similar problem reported about a month or so ago. That time it appeared that the savegame folder (or its contents) was tagged as "Read-only" for some reason.
The game saves should be located at C:/Users/<Your username>/Saved Games/<Name of the game>/.
I think its worth checking that neither folder nor any of the files there have "read-only" attribute.
E: lol that was exactly the solution Khris gave a link to. Err, well. ;)
