The PlayStation 3 version of the recently released Rock Band 3 has caused immediate problems for Kiwi gamers who have attempted to export their songs associated to Rock Band 2.

It seems we're not alone in the problem either, with similar reports coming from Australian and European players.

Owners of Rock Band 2 who wish to transfer their content to Rock Band 3 are required to enter a unique code found on the back of the Rock Band 2 instruction manual via the PlayStation Network in order to receive an export code. Many players have reported, however, that the downloadable exporter and the downloadable songs were not available as of Saturday morning, despite the fact that the PSN has accepted the required payment of $2.30 after entering the code.

While some of the content is reportedly now available (such as the free Doors DLC), many users who got in quick have now been left with invalid codes that can seemingly no longer be used.

The Rock Band international PS3 export site has been down since Saturday, and is still down at the time of writing. Game Console understands that only PS3 gamers have been affected by the problem. Electronic Arts New Zealand is aware of the problem, and is said to be looking into the situation today.

Something that is affecting all owners of the game, however, is the late arrival of the new instruments for Rock Band 3. Although the game software released on Friday, Game Console understands that the keyboards and pro guitar instruments are still a good three weeks away according to sources who've contacted local distributor Gamewizz.
