So, that means that there should be an unwrapper for the previous version of Safedisk. If the current version is 2.80.10, why not release the unwrapper for all versions up to 2.72.00? Plus, I don't think that versions older than 2.80 are of any concern to Macrovision - even software developers upgrade the Safedisk version used in their programs via patches.
Therefore I propose to release the unwrapper for SD versions up to 2.72.00
