Use ALT,CTRL,DEL to access the Task Manager Jojo, check running processes and make sure there are no duplicated instances of Riffworks running as processes. This has happened to me a few times and it makes Riffworks hang up like that. It usually happens when I'm too impatient to wait for Riffworks to start. The other thing to try is unplugging and re-plugging your ASIO device before attempting to re-start RiffWorks and or a re-boot

Failing all that, wait for Christopher Walken to turn up like Tom said, he'll probably give it an evil look and frighten it into working again :rolleyes:
