Kappie

I am a relatively new user and not a techie. I use insteon devices only. While the system, has been up and running for a number of months, I do not make many changes. Lately, I am having problems getting the application of launch . When it launches, sometimes it shows the ISY, UUID, URL and type which is a ISY994i. Sometime it shows the version (4.7.3) sometime not. It then shows system busy and when I enter the user ID and PW to access the it either does not connect or shuts down the application. All my routines work. I just cannot access the application to add an existing timer to a routine. Any help is appreciated.
