I purchased the Online version of DBpro, and it seems there was not any BSP converter.
As for GTK radiant, I just downloaded and will try shortly.
I was peeking into the examples for DBPro and found an example with a file called ikzdm1.bsp. This BSP is called from the program with the following sintax:
load bsp "ikzdm1.pk3","ikzdm1.bsp"
but this PK3 file is nowhere in the disk. Am a little confused. What is that? is it embedded into the bsp?
Didn't find any documentation on dbpro help, except that it is a packed world, but again, no idea of that structures whatsoever.
may the 3d force B with U
