I am not familiar with an error message that says "You have another tool running"? Are you sure that is the error message?
after the 30 days can i get back the settings previous???
Yes, you will just need to turn off the intercepts for the WWW Proxy Service. (GateKeeper --> WWW Proxy Service --> Sessions).
another thing: is there a new Puresight on the way?????
Yes, it will be released in the near future.
