Portal Error Message

Old Blue

Currently running version 1.02.32 mod 3.00 on an HDR T2.

When pressing the portal button, I get an error message dialogue box over the top of whatever is being watched at the time:

'an error occurred whilst launching the application https://www.humaxportal.com/'

with an 'OK' button.

Pressing the button removes the dialogue box, but it then becomes impossible to change channel or access the guide or media list with the remote. I can still select standby, however.
Thanks Black Hole - sorted.

I need to have a word with myself - I read that thread twice before posting and still didn't twig the solution.
