Answer 1

The most probably reason of not loading the solution may be because of the version incompatibility of the version of vs you are using and the one by which the solution(you are trying to load) was built. For example - You may be using the VS 2013 And the solution was built using VS 2005.

The solution is creating new empty solution and adding all the files you downloaded to load it successfully.
