The best way to test this is to decrypt an ITA thats already on the SD card on internal SD on the innotab.
(A game that was installed with the learning lodge (explorer park I think your version is called).
I do have vague recollection of that error being displayed even when the decryption was successful, as it checks for "uniquekey.bin" but if that file is not there it gets it from one of the partitions instead.
Why are you creating an the ITA with copy? it should be on the tablet already...
Don't forget it will only work for an ITA that has been downloaded for THAT tablet on THAT tablet, you can't decrypt it on a different tablet.
