The Slam It icon auto-populates this to the Max Bid section:
NaN
Additionally, I receive this message on Bidslam's main page:
Authorization Required! Your authorization with eBay has expired (or was invalided by eBay for Trust & Safety concerns). Please login with eBay to renew.
I've logged in with eBay a number of times as prompted by the message only to receive the same message again.

When I attempt to ADD SNIPE via the Slam-It pop-up, I consistently receive the following message:
"eBay Auth required. Please visit Preferences to update."

Hello Warren,
Thanks for the reports. They were helpful. These should both work ok now.
Please reply if you see anything else. Thanks!

Hi. I had 2 bids slated 2 place but both were missed (i.e. neither placed and both auctions closed naturally and without a bidder). They were:

Thanks.

Unfortunately that was my fault, a manual goof, it was about 20 mins before I caught it. Rest assured the system is stable.

Thanks!

You are welcome.
