It depends on when you bought BMax. If you bought BMax before they came up with that stipulation, you can make a DLL and use it as you wish as license changes cannot be applied retroactively. If you bought BMax after they came up with that stipulation, then you cannot make DLLs without a license.
Maybe so, but the older versions of BMax are just.... ew. It's like a disfigured, cancerous, rabid dog compared to a cute little bunny rabbit.
