Quoted from cabal:What software version are you using?
I Thunderbird has a Premium and he got it working, maybe he can give more detailed informatin how it works on the Prem/LE versions.
With the text Message "Welcome to the Munsters" it should be activated. Did you try it in Multiplayer? Then you need to activate it for each player separatly.
"Played Grandpa 2 Times" you went trough and it played the Lower Playfield in your LE 2 Times?
On the Pro i only need to play it one time, and next time when grandpa is lit, it will not play a 2nd time, it starts the secret mania instead.
Quoted from BowlingJim:I have a LE and decided to try secret mania. I took the glass off entered the code and the screen said
Welcome to the Munsters. I played grandpa 2 times but nothing happens.
What am I doing wrong ?
I had the same issue. Got the message Welcome to Munsters. 2x Grandpa then nothing. I also have an LE.
