I have recently restarted the game after a long absence and find that although I previously saved throughout there are no saved games and I have to start at the beginning, even though I was already in Mexico. On my computer all the files are there, but not in a saved games file and there is no autosave file. I get a message saying that Windows cannot access specified files, I may not have appropriate permissions, etc. I am the administrator and have all control on Windows 7. Please help.
