I'm assuming all other URLs and apps work as expected. WAG Can you try a different browser? Are you at the latest version software, which could of course be the problem? Have you checked iPad related forumns for help? Disable/delete all security related software. Do you have a return warranty? Perhaps there is a app conflict, did this occur at the beginning or later? As a last resort reload the OS software from scratch, then try MSN. Hope this helps.
Needless to say post model number and software versions and perhaps someone can help.
