AutoCAD 2013 does not open some DWG files from LT 2009

Hello Everybody

I have just upgraded to AutoCAD 2013. Now I have one AutoCAD 2013 and five copies of AutoCAD LT 2009. A strange problem started occuring after starting using of AutoCAD 2013. Quite a lot of files done with LT 2009 are not opening in AutoCAD 2013. When you try to open this file, nothing happens and a blank new drawing is opened by AutoCAD 2013.

I have DWG TrueView from release 2010 to 2012. These files opened perfectly well in 2010 & 2012. So I downloaded DWG TrueView 2013 and installed it to check whether my AutoCAD 2013 installation was faulty. These files do not open in DWG TrueView 2013 also.

I tried exporting the file to DXF in LT 2009 and then tried to open the DXF file in 2013. It gave a message that it could not read the file. The odd fact is that it is not happening with every file done in LT 2009. Some open and some do not. Also tried recovering the files - nothing happened.

In my opinion, this seems to be a serious bug in 2013. Any body else experiencing this? I have attached the problematic file.

Doesn't open for me either in 2013. No message, no empty file.
It does open in 2010; it's a 2007 format file, as expected.
Saving as 2010 format or R14 format makes no difference.
Audit /Recover, Purge / -purge (in 2010) make no difference.
Trying to Insert the file into a new, blank file (in 2010 and 2013) causes a fatal error.

Sorry.

Thank you jaberwork for being kind enough to test my file. It definitely looks like a bug in AutoCAD 2013.

We're having a similar problem with 2013, some of our xref's don't show up when open in 2013. If we try to reload them nothing happens and even if we detach and try to reattach it doesn't take. It doesn't even show up in the xref tree. Strange. We've gone back to 2012. Might have to wait for service pack. There's always something. Good thing augi is here so we don't think we are losing our minds.
