This is becoming a tradition here: raise money, then create a new project and abandon the people who once believed in you.
As I understand from Thomas's response to another Sumoling's question, Reboo is now Mediaplace.

Question: Is this project still active?

Hi, sure it is! Please contact our support at .................. and we will provide you instructions on how to download the latest version.

And here is Thomas's response to me.:
Reboo is a software we worked on in partnership, but it’s owned by a different company.
I don’t think it’s still around. Sorry about that.

No further comments :/
