To help us to troubleshoot, please go to ReValver Option window and enable One-Time session log, and follow the instructions. Obviously, this logging will be enabled only once, for the instance of ReValver that will be created next, so try to make sure that the next time you create a ReValver instance, this is the one that will hang. Then send the log file to me: mljunggren (that sign in the middle) peavey-eu.com I'm in the middle of doing some bug fixes, so why not one more? Thanks.
