MLeader causes dwg corrupt

[Louis G]

I created 2 different MLeaders, 1 with text and the other with a bubble including an attribute. Those MLeaders are in my template.
The Audit and purge command was executed with 0 errors on that template .dwg
After working on my drawings and saved to my X folder, when I re-open that drawing it gives me this message.
"Unable to open this drawing, it contains incorrect or corrupted information. The recover command may be able to restore undamaged material from this drawing"

Audit and purge command executed after recovering this drawing, no errors are found.
I am using ACAD 2010 with up to date udates.

Does this ever happen to anyone and what was a cure?
Thank you for your time.
Louis

I don't think it's any help or consolation, but Mleaders are proxy objects when a drawing is saved to a previous version.

Are you saving the drawings in the native 2010 DWG format? Or are you trying to have AutoCAD automatically save back to an older format DWG? I recommend keeping the native DWG format and use eTransmit or DWG TrueView to explicitly convert copies of the DWG to older formats if they are needed.

However, if you have multiple users accessing the files and everyone is not using 2010 this doesn't work so well.
