Just seconds after I emailed TT to complain, I attempted one last attempt to get this app working and suddenly it "appears" to work!! Registered no problem and even done a couple of test calls.
If you are having problems then try what I did
1) Unistall the app
2) Via "my account" send the pin to register
3) Install the app as usual.
4) Enter pin (under I have recieved activation code)
Not sure if its a pure coincidence or not... but the problem appears to have cured itself.
