Error message: Missing variables or other problems

Hello!
When trying to open two recently developed models I get the following message from Vensim: "The file has errors, there may be missing variables or other problems". When opening the model, half of the content is gone.
What do I do? I tried reinstalling the software.
Best,
Therese

Are there any other files in the folder with the model? Vensim does create backups, one of them might be available.

We'd have to see the model to say more.
Generally, there's a backup - if you have fred.mdl, there will be a fred.2mdl - rename that to fredBak.mdl and try opening it.
This kind of corruption is extremely rare. What version & operating system are you running?

Tried to open an old version of one of the corrupted models, to rebuild the most recent additions. The same error then occurred after a while, and this time there was a back-up. Nevertheless, the back-up has got the same error.
I have the macOS 10.12.6, and just installed the last version of VensimPLE.

Are you saving the model into DropBox, OneDrive, Google Drive or similar?

In the model you emailed to us, change
Code: Select all
"Mercury
in runoff" = A FUNCTION OF( Soil damage)
~

to
Code: Select all
Mercury in runoff = A FUNCTION OF( Soil damage)
~
~ |
Does it load ok now?

That seems to be one of the variables missing when I open the model?

Change it in the .mdl file, using a text editor.

Thanks for having a look at it! Still doesn't work though, even after changing the variable in the text file.

Its the same, and the model is still corrupted.
