Thanks, Annatar, it was right where you said it was. Strange that my search didn't hit it, I have hidden and system files visible.
Anyway, I put a zipped file up on my web server, here's the link. http://mott.home.dyndns.org/sins.zip
If it doesn't work put a www at the front, I don't remember if I had that in my domain name or not, and I can't check from inside my network.
I included a text file telling which planet the fleet is at. I have two different save games, same fleet, same ship, just different planets.
For reference, here are my PC's specs:
Intel Core 2 Duo E6850 @ 3.0 GHz
2.7 GB (don't ask) 800 MHz DDR2 RAM in dual-channel mode
PNY GeForce 8800 GTS 640 MB (NVidia driver version 7.15.0011.7116)
Windows Vista Ultimate 32-bit
1 TB Seagate SATA-300 hard disk
Nothing is overclocked, everything uses factory settings.
If any more information is required, just let me know.
