Doom64 dosen't work in Doombuilder2

I tried to start up Doombuilder 2.
Placed D64_build in the cfg folder. come up with this error

"Unable to load the game configuration file "D64_Builder.cfg". This configuration is not a Doom Builder 2 game configuration."

Where did you come by that config file and can you upload it somewhere for inspection?

Would that be the old DB1 config for Doom 64: Absolution TC? If so, well, I'd venture a guess that it's because it's a DB1 config and will most likely not work with DB2. I've used the config in DB1 before and it should work (last I remember, anyways).

Yeah, It is working for me right now on DB1

Here the link to the upgraded D64 cfg

It got me past this:
"Unable to load the game configuration file "D64_Builder.cfg". Error near line 662: Spaces not allowed in key names."
