Did you try re-assigning the hotkeys for quick save/load? If so, ctrl-c wasn't a typo. <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
Maybe a clean re-install would help? Zip or otherwise backup your saved games folder to another location first, just in case. Then un-install, re-boot, shut down all non essential programs (especially anti-virus), re-install the game. Maybe start the game and see if you can quick save(games saved under the 1.34 patch will not work in game version 1.29, but you can try in a new game). After this, re-boot, shut down all non essential programs, install the patch, re-boot, shut down all non essential programs, start the game. This procedure is a bit over-cautious, but the best way to avoid install problems.
