Hello,

I'm afraid that .jude/.asta files are upward compatible and you must have received a dialog when you opened your .jude file in Astah Community to warn you "This file was created in older version and if you edit this file in Astah Community, it may not be opened in older version anymore."

It may be impossible for us to fix the file to open it in JUDE/Professional 5.x again but at least we can try and look, so please send us your .jude file to us.

Again, we cannot assure you anything at this point, but we will see what we can do for you.

Thank you.
Satomi
