Dave, thanks for your reply.
I just created a DXDIAG for this XP machine and just brought my Win7 laptop in here to do the same. That way they will have info on both machines that Caesar 3 crashed on.
Did you ever get a resolution to this problem? I'm having the exact same problem myself (have tested my save file on windows XP, Windows 7 and in various versions of WINE - all with the same result: CRASH! at the end of aug 162BC in Procurator Dangerous)
I switched pc's a week ago and just now installed Caesar 3 on my new pc so that I could go back to see where I was able to get past the freeze glitch in the GOG version.
I managed to make it past Aug 167 BC by using an old sav file from when I used to play this game from the original CD.
The closest I could get to being a Procurator around 167 BC (where the glitch is in the GOG version), I was able to find and use an old sav file that starts in Oct 166 BC and it's playing as "Peaceful" but should get you through the 167 BC glitch.
PROCURATOR-peace0015-GOOD-FILE.sav (Oct 166 BC - Peaceful)
** You CAN rename this file and also place a copy of it in your Caesar 3 folder. I gave it this name so that I'll know where to start whenever I play the game again down the road.
NOTE: I still have many old sav files from this game from a few years ago so if you run into a glitch again, just let me know the YEAR and the POSITION (curator, etc) that you are playing so that I can test my old sav files out and try to get you close to where the game froze.
So if a Moderator will contact me via my acct email address and give me permission, I will gladly share the above file to help others.
Also note that I discovered that the GOG version of Caesar 3 is missing a few files which I found on the Original CD. I spent time comparing several files last year and I placed the missing files into my directory so they may possibly enable the game to be run without any glitches but am not sure since it's been a little over a year.
PS. I was happy to see that this game works on Windows 7 which I am now using!
