Can't Load Old Schematic

Opening my mouth where I might not know what I'm talking about, but here goes anyway! 

If you open that file with a text editor, do you find "SUPPLY1" listed twice in that part?  It may be as easy as using your editor to change that name, or delete the extra definition line.

Make a backup first... 

Doug, I actually tried that right after I posted the question.  In the first attempt it just went to another error involving the same signal, so I deleted that line also.  The schematic now loads and looks correct, but I'm sure there are missing connections.  A better 'hack' at this might be to change the signal name on these 2 lines to some new, unique name.  I haven't tried that yet.

The 2nd error message is: <instance part="SUPPLY1" gate="GND" x="332.74" y="172.72"/>.  Note that this has coordinates in it, which I presume would indicate where the particular connection to this signal occurs, but what coordinate system is it?  I can only set the grid to 'normal' units such as inches or millimeters.

The coordinate system for sch file is millimeters

You can verify this for your self. Set the sch grid to MM. next locate a

part on the schematic, say R1 and view its INFORMATION. Record its xy

location

Now look for the part in the file in the 'instances> instance' section.

It will be towards the bottom. It will have the same XY there.

Quickest way to find the right line is search in the file for "x="60.96"

inserting the x you noted from INFORMATION. THere will likely only be

one fine result, the one you want.

Setting the grid to inches, performing a save and then inspecting the

file again, there will be no change to the xy location of the part

proving it's mm.

Does this tell you anything?

Thanks Greg

The XML looks well formed. For some reason Eagle permitted a part of the

same name or made an error when writing out during the save, Anyway your

solution is fine.

Since about v6.5 Jorge reports there have been more checks made when a

board loads so maybe this is why it has shown up now.

All the best
