BCL files do not appear and sizing run failed

edit

Good morning I am testing a number of BCL templates, both from the online library and from the website.

The web templates I have placed them in the Measures folder of Open Studio and after updating, I have gone to ''Components and Measures'' -> ''Apply measure Now'' and none of the measures I have placed on the folder appear. (As it is obvious the folder comes perfectly with its .rb files).

On the other hand, when I use an online file from the open Studio library I get the following error:

Could someone explain me how to solve these two things?
