It's the same driver as previous one(9th March one),not even worth installing,all they fixed was an error to do with certification with the installer.
These are still not WHQL drivers,if you have installed the previous driver, just leave them installed until Creative release an official WHQL driver.
Btw read this over at Creative Forums,
Just adding to Jason's last post:
From the other topics, the certification in question is not the WHQL certification. The current drivers are still not WHQL signed. The certification in question has to do with the installer package, per Cat.
Why the drivers aren't WHQL signed is supposedly forthcoming information. I wait patiently...
