With regard to the NevoStudio messages in this thread, (for Q50 & S70) not for Nevo SL, UEI took down the server for two things.
1) Registration no longer works; you cannot register your version and it really doesn't make any difference because the services after registration are also no longer available. See below.
2) Using "Model-based-setup", which was the best feature for adding a device also no longer works. You have to create a new device manually and learn the IR codes or paste them in via some other source such as a manufacturer spreadsheet, etc. Or you can choose "Browse for Devices by Device code and Brand which is a crap shoot and has way too many codes sets to make it easy.
3) On this page, there area few other options which will work without registration. Choose what you feel like working with.
