Where did my save file go..

I've been playing the game for awhile now and when I've gone into the game to resume playing the only options that come up are new game and my save file isn't there..? Not sure what has happened would really like some advice and guidance as to what to do to get my saved file back please

Lele123 : I'm not sure what happened. Have you been saving your progress using F2? If so, click F4. If not, then I think you'll have to restart. It's happened to me before too, but there's currently no way to regain lost data. Did you delete anything to do with the RGR plugin? That may have contributed to the loss of data. I hope you can get playing from your save point, but I think you may have to restart from the beginning. Sorry!
