WHen I click to update I got this message "Downloading Google USB Driver package, revision 4 File not found: C:\Program Files (x86)\Android\android-sdk\temp\usb_driver_r04-windows.zip (Access is denied)" and when I launch the AVD i get "invalid command-line parameter: Files. Hint: use '@foo' to launch a virtual device named 'foo'. please use -help for more information" I been following step by step instructions for the book for beginners guide to android programming. but this AVD and SDK are acting up. When I try to make a new project, it wont let me select build now. I have no idea whats going on now.
