I haven't used this in a while, and it looks like it not free anymore??? I used to have 2 accounts - one for each of my eBay accounts. All of the sudden I can't log into one of them anymore. And there is no password recovery? Any help would be greatly appreciated!

It's free. If you check the front page of the website, you will see the following statement:
"Myibidder.com (originally Myibay.com) is a Free auction bid sniper and management service for eBay."

If you forgot your eBay password, you can always go to eBay and reset it there. They have an easy procedure for this.
