Trouble opening BWG files

I believe the BWGen is for PC. I'll post some links that may help you:

Copied from another post:
Running the BWGen on a Mac:
1)...there is an open source program that runs on BSD Unix (on Mac OS X) called SBaGen which is essentially the same thing. you can only run it on the command line from a Terminal window, as it has no user interface to interact with, but if you're comfortable with that, it's a very comprehensive app with tons of presets and multiple options for configuring your sequences. it's well documented in the ReadMe's that come in the download.

you can find it here:

http://sbagen.sourceforge.net/

..there is a fair amount of documentation and discussion about the program on these pages. and there is also a discussion list you can subscribe to; from this I've noticed that the app continues to be supported by a committed developer.

2) 'Virtual PC' emulates a small pc into your mac, like would any other sofware (photoshop, word,etc...)
it can send BWGen to your sound card, so your trouble wwill be fine.
