Hi
Sounds like you may have moonphase set up, I am assuming you have a simuDB i.e it ony has a blue colour.
Other than moonphase or the simulation being set to cloudy days you will need to look at your set up graph. As there as so many setting for the simu's it is hard to diagnose by guess work, but if you can send me a copy of your profilux data file I can tehn upload it to mine and see where you are going wrong.
This can be done in file menu, you cn then save you settings to your pc and email them to me at
sales@aqua-digital.com
Please give me 72 hours to look at it for you.
Not all the LED lights from profilux are simu's only the ones that flash, if you have a quick glance at my site you will see the difference as to what they do.
Regards
Michael
