I played a lot to get there , i will appreciate if anyone will help me.
Thank you

I take it you mean "saves" and not "savings"?

Anyway, try right-clicking your save folder, then Properties, Previous Versions tab and try to extract an earlier save.

Whether that works or how close that will get you depends on a lot of factors.

Try an Autosave mate. If there's not, you can ask for a savegame file, someone may have been playing just the same quest.
