Just wanted to let you know that I also got the working replacement disc from codejunkies.uk for free!
I contacted them via email, but noted that I bought the now defunct version from play-asia.
They wanted some proof of purchase. A screenshot from the play-asia account was sufficient.
Afterwards the sent me a new version (in a dvd case) absolutely free (and I live in Germany!). It took roughly 3 business days.
They just wanted the old CD back, once I received the new version.
After the new Version arrived I put the old version in some small padded parcel for 1€ and it went off to the UK.
The new version works like a dream (until Nintendo jerks again), but it should be noted that the new version works error free like the 1.06b with the gamecube did (no freezing during play/boot), so they corrected the bug with the last wii version.
