If you're having trouble authorising your free copy of Bass Master using the license provided in your account area, it's most likely that you're pasting the serial number from your Plugin Boutique account page incorrectly. This must be copied from your account area on Plugin Boutique directly, including the ---START--- and ---END---. Avoid copying this into a word processor before pasting into Bass Master, as this may change the formatting. It's also important to note that webpage translators may translate parts of the serial number. In this case you will need to turn the translator off.
You can find your license for Bass Master in your account area at Plugin Boutique here.
