HELP! Recovering previously saved drawing

So I spent 4 days working on a profile last week. And this morning I opened it up and accidentally erased the alignment, saved and closed the drawing (I must have thought it was in another drawing, and I wasn't paying attention).

Now the profile is gone and I'm wondering if I can open up a drawing that was saved before I did this mix up. I checked my autosave path, but the path doesn't exist. So I don't know where it's be autosaving to. (I made a new path fyi).

Do I have a hope to recovering from my stupidity?

Can you locate the BAK file for the drawing?

Yes, but.. isn't the .bak created each time you save a drawing? SO it would be the same as the drawing I'm in correct? (It has the same date and time in the date modified). I'll open it to be sure

I opened the BAK and the alignment isn't there...

however my profile (minus the grid) is there

Well you can only go so far back in time with this method.

oh darn... thanks for your help anyway

For future reference, at the end of each day I save the drawings to my personal drive space on the network.

1.) Incase of hardware failure etc.

2.) Incase I need the copy of the file I started with that morning.

If you do not have your own drive space on a network, create a seperate folder on the network or your local drive, mayby a flash drive.
