Jeez you really do have an issue with your net connection & reliability!!! There's something definitely amiss there. I'd contact yur isp & complain about inconsistent results. Seriously you are receiving inconistent results in your dwnlding if you have failed at instlling 2 apps via the internet. I wouldn't recommend updating over the net in future but 1st dwnlding the standaline installers.
