I had the same problem but ive forgotton how I fixed it
I still cant remember but its probably this: If you have Winows 7 try going into the games folder properties and uin checking the read files only box.
Some ppl say that win7 setting all its files and folders to readme only is just a graphical bug and has no real effect. But ive had several games that wont save which are fixed when I remove the read me tick.
If we're at it... Why the eff does cc run perfectly in fullscreen (widescreen option) on my desktop but when I use the same bloody settings, it only runs windowef on my laptop? Both are win7 64bit home premium machines...
Any chance that I can enjoy the game in widescreen fullscreen on my laptop?
