>>> I have J bridge 1.65c, officially the latest on 12-12-2014, ALREADY bought it, and Sampletank 3 installed. Does not work with BIAB ....

You need jbridge 1.73b or higher. So if you have an older jbridge, you need to update it. Of course the jbridge that you can get with Band-in-a-Box is the new one, and you don't need to update jbridge, as it works great with BB 2015.

********* THE INFO BELOW ONLY APPLIES TO PEOPLE WHO ALREADY HAD AN OLDER JBRIDGE, NOT THE PEOPLE WHO GOT IT WITH BAND-IN-A-BOX ****

You can update your existing jbridge here: http://jstuff.wordpress.com/jbridge/betaupdates/
Note the list of fixed issues for the jbridge update:

- Several minor crash / bug fixes.
– experimental audioMasterSetTime implementation.
– experimental speed improvements in some IPC structures.
**** – fixed an issue where bridging files would not be loaded when using Band In A Box. ****


Have Fun!
