Can not upload reports to Report Server

I don't quite know the right answer for you, but from my limited experience I've found that if I re-download the version offered by the PBI Report Server web portal, that seems to work best. I am curious though if these interim bug fix releases are making it harder to know which is the "right" version for any given release. Might be that we need an indicator somewhere in the server application to inform us what version is right.
