Band In A Box 2018 will stop responding and shut down if I run audio (mp3) and activating a style at the same time.

Basically I used ACW (tried both, standalone and integrated) to make a backing track, saved the changes and it won't allow me to activate the style _JAZZHOP.STY at the same time playing the audio file.

The thing is, if I disable the audio, then it works.

Then I loaded the same file in RB and it works just fine.
Is this a bug or am I doing something wrong?

Another couple of problems... in RB I try to load the Helix Native VST... it shows the listing in the applet but it does not appear. This is the (x64) version. Also, the tracks meters won't light up during play. The only one that does is the master channel at the bottom right.

can someone help please?

The software is the latest releases.

Thanks
