I don't understand what you mean by the "blue" fat channel. If that is a reference to the studiolive mixers, I don't have one. I have tried to drag the fat channel from the browser directly onto a channel, and have also clicked the + on the insert on the channel and added fat channel that way, and I can still only see 5 compressors and 5 eqs. It seems to me, that when I activate my purchased items, when that's done, the window should change and say something like your items are now activated. Instead, I see the blue loading bar fill up for each compressor and eq I don't have, and when the bar reaches full, it flickers and on to the next one. When they are all complete, nothing happens, the window doesn't change. I can click the activate button several times with the same result. I wonder if something on my computer is messing with studio one. I am using a macbook pro laptop, runnng mojave 10.14.6, I use a steinberg ur44 interface, and a 2tb external harddrive which studio one 4 and eveything in it is stored (except for my presets which are saved on my computers harddrive). I was wondering about uninstalling studio one 4 and reinstalling it, but I am afraid that may use up another of my activations. Any advice on this would be appreciated.
