Hey I just tried your save editor and it froze and closed after about a minute of not responding.
I tried it in administrator mode too and get the same thing.
I tried extracting the save file within the .sav and got the same thing (not sure if I'm even supposed to do that)
I only tried to mod the max money to 90,000 and money being carried to 20,000 and it still did it.
It seems like only your old save editor will work for me.
I'm running Windows 7 Ultimate Service Pack 1 64-bit, if that means anything to you.
And in case you want to look at it, here's the save. http://www.mediafire.com/download.php?4y9q312ekaq90a9
