I installed Psiloc total irRemote 1.41. After it showed "Application expired", I removed it. After long time, I re-install it, but it still shows "Application expired" and exit by it-self, I can not go to Registration form to register it ? Or using it by a demo version ?

P.S. Can I upgrade my 3650 firmware from ver2.5 to ver3?

An email to Psiloc's technical support asking for a trial registration shuld do it. They'll be able to advise the best way for you to have another trial.
