Alpha Client will not update after 44.1 megabytes

I have recently been added to the Alpha Client testing crew and the first error has come much faster than I first thought. After installing the Alpha Client, it proceeded to open itself to begin updating. When the updating screen came up it began to download, it updated until it reached 44.1 megabytes and crashed. The Client told me that an error had occurred and that it will restart, and it went on and on with no avail. I cant seem to understand the problem. I ran the client through my 360 Antivirus Sandbox tool and it began to work. What I noticed was that 4 different clients were in use for it to run. League Client and 3 LeagueClientUx. I don't know how to replicate what my Sandbox is dong but id like to know how I can fix it. Does anyone have any ideas?
