Umbraco doesn't works with IIS 7.5 medium trust - Operation could destabilize the runtime

That's correct, Umbraco doesn't work under Medium Trust. You need to find a hosting provider who will allow Full Trust.
See http://issues.umbraco.org/issue/U4-919
Try using 4.7.1 or 4.7.2, as those runtimes do work under Medium Trust.
HTH,
