A few days ago, photosynth told me it has "expired", and I can't open the app properly, so I had to reinstall the app. After reinstalling, I am no longer able to view the pictures taken before even though they're still in my phone. Did anyone encounter this before? Did you have any luck restoring the pictures to the app? 

ps. the "refresh library" option did not work.

Thanks

By the way, my phone is NOKIA Lumia900

Please see this discussion: http://photosynth.net/discussion.aspx?cat=e57bdda7-ff98-40a1-b2ae-529b0213c2b8&dis=e391cbe1-395d-491f-a398-deaaa201de2b

This should be a one time error, but when you uninstall a mobile app, all of its offline data is deleted along with it, which re-installing the app cannot restore.
