constant re-registration. every time i load it. and every 5 minutes. and the demo audio constantly telling me to buy it, despite the plug having my name on it!

have re-installed several times.

this plugin is useless to me right now.

Bitwig 2.4, windows.

That sound like Microtonic has a hard time saving and loading the preference data from the registry. Are you running under a restricted user account or have you run any utility that might have changed the access rights to the registry?

Also, some standard questions, are you running the latest version? Do you have both 32 and 64-bit versions installed?
