I have a question that just showed up on my show computer. When I click the output to lights I get a pop up that says "another process seems to be outputting to the lights right now, this may not generate the result expected" I have no other program on this computer for lights. I checked my programs and deleted older version of xLights which caused issues. I lost all of my sequences and setups. I tried to retrieve them but it did not work so I have to redo all my work. Downer! I'm glad that I don't do musical sequences so it takes 2 -3 hours for a 5 min. sequence. Main thing is that popup about the other output to lights, I do not see anything that could cause it, Any help is good, Charlie J.
