error error

[doriano]

Good evening to all
I try to open a product made a few months ago but it does not open and gives me this message inside a window.
error - osm_al033 impossible to open the document due to an internal error.
Does anyone know anything?
Thank you.

should be a version problem
try to open the file with a text editor and search for the word "release" and check with which version the file was created
