Tworavens "Estimate" button doesn't works fine

[Michel Bamouni]

HI,

I successfully install tworavens and connect its to my dataverse 4.8.6.
I upload 50by1000.dta file and I get the graphic with var1, var2 and var3.

But when I set mouse over var1, and click on Dep Var and I click on "Estimate" button, I get popup with the message "Warning : data download is not complete. Try soon".

When i try latter I still have the same warning. 

The screen I get is join to this post.

How can I solve this?

Best regards,

Michel
