Sounds like you may have fallen into a trap in terms of compatibility. Which is what Mario was suggesting. Best I can tell Kontakt went to 64 bit with Mid v5 (~v5.67). If yours is older than that it may be 32bit and will not work in BIAB. If so get the free Kontakt 6 player which is 64bit .dll and still not yet VST3, and try that? I use full Kontakt 6 with BIAB and last time I checked it was functional.
