Status of Special Text Boxes Pro

Could someone tell me what the status is of Special Text Boxes Pro? I looked on it’s EnvatoMarket/CodeCanyon page and it’s marked “Item no longer available.

I have quite a few pages on my site that use this plugin. If it’s no longer being developed or updated, what are my options. Can I simply revert to the free version? If so, how do I do that without screwing things up? Or are their alternative plugins?

Thanks!
