Upgrade to the new OS4.0 on my BB7290.
Everything has restored correctly except for eFile.
I try to do an install and nothing happens.
Any clue why I can't reinstall it?

I've finally got it back!

Now, I'm unsure as to what viewers it should have by default as it use to be able to open a *.doc file but I now get the message that there is no application associated with this file type.
