Thanks again for the info. I did all the steps you told me to do. My FL Studio recognises the plugin version of Band-in-a-Box, but, there isn't any option to add the patch file on it. Howerver, on the main program version of Band-in-a-Box there the option to add the patch, but on the plugin version not. What do you think I'm doing wrong? I attached some screeshots so that you can see what I'm refering to. Thanks again.
