I just downloaded a trial version of volt db. When I try to run the first test project with sudo ./run.sh I get an error "unable to open licence file" -- contact Volt to request a licence. In the registration info for volt db it says that running volt db requires a key that will be emailed later. I have not gotten an email with a key yet and have not added a key to volt. Is that why I am seeing this error? If so, when will I get my key? How do I add it to volt? If not, how do I fix this?
