Motorcycle title, signed but not transferred, "open title"?

Bought a motorcycle in a box. Rolling frame and box full of parts. Came with title. Rebuilt it and it's now road worthy.

Need to get its title transferred, bike registered, plate, and inspection.

The title is an Ohio certificate of title. Original. I live in Texas. Signed by the owner and dated, price listed, except that it was never actually transferred. So it's dated 2011, signed by the listed owner on the title, but the buyer field was left open. So, it's an "open title".

I think I'm past the 30 days to transfer it...

What are my options?
