Cannot install any package on JuliaPro 0.6.2.2

Hello everyone,

I need some help.
I’m on windows 8 and I just installed JuliaPro 0.6.2.2
I cannot install any package. For now I only tried with YAML, Plots and Cubature and none of them work.

They all give the same error:

julia> Pkg.add("Cubature")
INFO: Cloning cache of Cubature from https://github.com/stevengj/Cubature.jl.git
ERROR: Cannot clone Cubature from https://github.com/stevengj/Cubature.jl.git. user cancelled certif

(::Base.Pkg.Entry.##1#3{String,Base.Pkg.Types.VersionSet})() at .\task.jl:335

The error looks similar to the one discribed in this topic except that in my case it’s not Plots specefic.

Many thanks in advance

Sorry,
I realized this must be a duplicate of Git / Pkg Error.

Or you can simply link to the Git error post and leave this thread as a reference to other people.
