Hello Luke,
As per the instructions on the web page, please do not use our site to guess your eBay password. You've tried 3 different passwords almost 20 times in the last 24 hours, so eBay locked your ID of our service temporarily for 12 hours.
Please first verify the password at eBay, but do not use the auto-complete.
Then you can enter it on the BidSlammer Preferences page.
