"File not avaiable on site" when I try to download the zip.

Hello Martin,
Thank you for the report. We'll check into this and get back to you ASAP.

The file path was corrected, so you should be able to download it now. Feedback would be appreciated! Thanks if you can help.

Yes, I downloaded and unpacked it successfully. The Slam it button appears on auctions. I have not used it in anger yet.

Haha, I haven't heard that phrase before. I hope that wasn't sarcasm and you are enjoying it so far. :)
