AutoCAD 2013 Drawing Conversion Help Needed

I have taken some work home to do over the weekend but stupidly have forgotten to save it in a previous format.
I have 2013 at work and 2012 at home. I thought I had done it but it turns out I had done all the reference drawings I sent but not the only drawing I actually need to work on.
So could anyone open my drawing and save it as a 2010 file so I can get a bit of overtime in over the weekend.
Many thanks
Andy

free viewer from autodesk can convert it for you: DWG Trueview 2013

This can convert new 2013 files to any older .dwg

I use it every day for work where we still use 2005 files and recieve architects plans in 2012/2013! 🙄

+1 for true view. One of the few things that Autocad does well.
