I have just purchased an Acer a500 and being new to the Android operating system I am going insane just trying to use it. Firstly I connected onto a wireless network which worked fine, then I had to download updates for the built in games, Golf and Sparta. Everytime I hit the update button it commences and then crashes out saying that update failed. I also tried to use the Android market to try and get a file manager but it does not let me down load and come up with a message requiring me to force a stop. Can someone please help???
