D2:LOD The file do not load to editor anymore

[old-aa]

Hallo,
I edited my .d2s file twice on the editor, but after some gameplay the file is not opening anymore. Any other files, not edited before, can be opened fine. Tried all the tips found here (stripping the hero from the gear etc.), but still not working.
I play D2:LOD, not the Resurrected.

Thanks for any help.

o..a..
