the method database is empty

Question

I am currently working on a project
 of DAP in construction products. I follow the manuals and examples of the OpenLCA software. I install the databases and methods (OpenLCA LCIA 1.5.7.)
I have created the processes and product systems. And when it comes to "calculating" I don't get the method database.

Any comments will be highly appreciated.

Thank you

what do you mean by "I don't get the methods database"?
1.5.7 is about two years old, you could consider a newer method pack btw.
