Good Morning.

 

I am having a similar problem.  When trying to open by original file I get a pop-up saying "Drawing file is not valid."  So I tried to go to Explorer and open the .bak file.  I chose open with AutoCAD LT Application.  FYI, I'm using AutoCAD LT 2018.  I tried searching for AutoCAD DWG Launcher (which is an option I get with I choose open with on the dwg file) but nothing comes up.  After doing this I tried making a copy of the file and changing the name and giving it the .bak extension.  When I try to open that with AutoCAD LT Appication I get a pop-up that says "Cannot fine the specifice drawing file.  Please verify that the network drive is available and the file exists."  This all happened this morning.  I was working in this file, I saved it, and then closed it (as well as all the programs I had open at the time)...I had to reset our server.  After the reset I tried to open the dwg file and that is when I got the "invalid" pop-up.  I am not having trouble opening any other files, just this one.  And I tried to open it on a different computer but got the same "invalid" message.  This file has a lot of needed drawings in it.

 

Please help!!

 

Sincerest thanks for any and all help.
