Hello,
I just read on Yahoo Groups that Fits Liberator 3.0 has been released for both the Windows and Mac platforms. Also, it looks like it is now a stand-alone application and does not require Photoshop for it to run.
I just downloaded and installed it, opened a FITs file in CS5 and all appeared well!
Here is the link:
