Renumbering of tracks

Hello,

following problem. I have uploaded to a Vault 2i a double album with classical music. Unfortunately it is not splitted in the vault in two cd, instead put in one file. As a result the sequence is now track 1 from CD one, followed by track 1 from CD 2 and so on. The renumbering of the tracks in zhe "Extrfa" tab of the software was not sussessful. What do I need to do?

As I do have thew sofware just fore 4 dfays. please do not except to much knowledge,
