The plug-in stalls upon activation.

I tried installing it from the plug-ins installer and uploading it directly via FTP. It’s the same. Whenever i try to activate the plug-in it just stalls and nothing happens – if i wait long enough i end up with a “Failed to open”.

Any idea on how i can fix this? I was really looking forward to using your plug-in.
