I also got the problem when trying to activate this plugin in the WordPress. The error message is “Plugin could not be activated because it triggered a fatal error.” I used Safari (for windows) browser.
Also getting a fatal error message using WP2.5RC2 on OS X/Firefox2.0.0.13. Tried updating plugin via auto-update and manually – same result.
Just do a local unzip of the Plug-in with directory = filename. Then upload the directory to the Plug-in map on your server location.
Then start WP and go to Plug-in Administration and activate it.
