Every time my veiwer tells me I need to update, ether right before logging in or while im already logged in. ya know that pop up you get that says you need to update? well i click on that, it starts to down load and install etc. it gets to like the last 90% and then this error shows up. EVERY TIME!!! the only way i can up date is if i go to the page and download the viewer from the home page. and sometimes it takes a few tries to work. Does any one else have this problem? how can i make this stop happening?
