If you set up an account which you don't have to use it. When you enter your user name and password they will come back you can also manage them from there website if you have done so. If you did not then you will have to set them up again.

Same happened to me too.
Go to your Viigo Account on your PC make sure your feeds are all there.
Then login to Viigo on your BB and update all channels.
However when you started up Viigo on yr BBafter yr upgrade it should have asked you if you have already an account. Then login and refresh.
