Greetings,
even tho this is old post i'm going to post my solution:
I solved this riddle by putting -name=nameOfYourProfile to startup parameters of Buldozer.
Now mine Terrain Builder settings look like this:
.exe file path: P:\buldozer.exe
Launch parameters: -buldozer -window -cfg=p:\buldozer.cfg -name=Pfc. Roys
Data Directory: P:\
Everything works just fine. Cheers!
