I used JBridge to access 64-bit plugins while I had BIAB 2018 (520), and it worked. Yesterday, I did the update to 2019 (610)

BIAB(64-bit) opened fine, and allowed me to load a .MGU song I created under 2018 using C_EAGLES.STY, and play it back, using 4 MIDI tracks, and one RealTrack. Under BIAB(32-bit) however, I got the following error 3 times as I opened the file:

JBridge 1.75
File not found, is C the correct path?

If you moved or deleted the original plugin you will need to re-create or delete it bridging file.

The song did play back, although the MIDI instruments were much quieter. Looking at my config in both programs, I noticed that I had to add VSTi's to the 64-bit version, and it accepted them as they were added.

But in the 32-bit version...... all of the plugins that I had previously added from 2018 were listed, but could not be chosen.
The only Default Synth that works is CoyoteWT. Selecting any of the plugins in that list, generated the exact same message as above. So, I tried to manually add those VSTi's ---- same error as above, but now with a second message:

Sorry, Band-in-a-Box can not make connection with <name of the plugin>

Any ideas on how to straighten this out? It was all working in the 2018 version, all I did was the update.
