I just got an 830 a week ago and one of my first downloads was to put UC browser on it since I like it on my 900. All worked good until this weekend when I finally got an SD card and moved most of my apps and games to the card. At first everything worked just fine included all files that had previously been downloaded with UC. However once I tried to download a file after moving to the card things went downhill. For the newly downloaded file UC said it couldn't open it. Then trying to open one of my older files I found that no longer worked eventually having to delete every file I had already downloaded with the app. I tried deleting the app and reinstalling but it wont install now. It just keeps going to the "Attention Needed" bit and never installs. I've seen others complaining about issues with the new update but none specifically mentioned they had the app on an sd card.
