I have a project of one of my students, but i can't open it on my computer. There is also an older version with the same puppet which opens without problems.
Does anybodyknow - what this error means - and how i can correct it. I can also send the project if you want to have a look inside.
All I can suggest is try opening it locally.
What do you mean "Locally". My student sent me a Zip Archive with all the data needed. And i open it on my computer locally.
You're doing it right, I was hoping it might have been a server issue.
