Wii--Sticker stuck in cd slot

If you are technically inclined you can take apart the entire unit and remove the cd player portion. Once you remove the drive itself you need can carefully take it apart and remove the sticker.

But keep in mind you'll void the entire warranty if you do this and you'll pretty much be flying solo because there isn't a lot of documentation on the internet yet about working on the WII.

My recommendation would be to take the system into hollywood video and demand to speak with a manager, explain to them the issue and if they don't assist you call their corporate office.

The damage is their fault, they need to take care of it.
