Thanks for taking the time to download and try the new beta version. Sorry to hear you are having a problem getting it to run.

It would be helpful to list the exact steps you take to install the new version of the screensaver in place of the old version. As dsanfili noted, you can double-click the screen saver in the disk image file and the Finder will offer to replace the current version (with authentication).

There are two locations where the screen saver can be installed: /Library/Screen Savers/ and ~/Library/Screen Savers/. The first is located at the top level of your boot drive, and makes the screen saver available to all user accounts on your system. The second is located in your user directory (available in Lion by holding down the Option key when selecting the Go menu in the Finder) and makes the screen saver available for just your user account.

The link/alias to "Screen Savers" in the top level of the MarineAquarium3.2 disk image points to the system directory (/Library/Screen Savers/). Dragging the screen saver to it is the same as dragging the screen saver to the /Library/Screen Savers/ folder in the Finder. On Lion, I haven't had success replacing the screen saver located there by dragging and dropping the newer one to that link/directory, even after authenticating. I have to double-click the screen saver and let the Finder replace it (after authenticating), or remove the old screen saver manually (drag it to the trash, empty trash, possibly requiring selecting a different screen saver in System Preferences first) before placing the new version in that same folder.

The "You cannot use the Marine Aquarium 3.2 screen saver with this version of Mac OS X. Please contact the vendor to get a newer version of the screen saver." message seems to be the default message displayed whenever there is any problem trying to load a screen saver. One case where it can be triggered is when Mac OS X gets "confused" about the the location of the screen saver. For example, if you have the screen saver installed in /Library/Screen Savers/ and selected as the current screen saver, then move it to ~/Library/Screen Savers/, you will encounter this message. The fix is to open System Preferences, select a different screen saver, then select the MA 3.2 screen saver again.
