i was having the same problem with sequel, running vista, but getting the license control center and running that setup didn't help
EDIT: i'm an idiot-i didn't see the window saying to restart the computer. now i've got a new problem-
application 'sequel 1.x' has caused the following error:
No eLicenser connected.
opions.......connect a valid elicenser and click retry(i didn't get any kind of elicenser thing to connect)
