Hi Shahira,
All of the formats (including *.tb0) are described in the Blue Kenue Manual. If you have created a file that is not loading into Blue Kenue, please send it to me and I'll have a look. Off the top of my head though, it sounds like you are missing one or more things in your *.tb0 formatted file... in this case "EndHeader" in the header of your file... maybe other things too? It is hard to tell as you haven't provided an example that won't load.
On a side note, if Blue Kenue is not able to do something that you want then please be patient or throw gobs of money my way!
At one point I was thinking about creating a kickstarter project to try and find money to support development work... if there is any interest in that then I'll pursue it...
Kindly,
Alan
