Yes it's very strange. This morning I completely uninstalled AHlll and then checked the registry to remove all obvious traces of the program. Then I ran both Advanced System Care and CC Cleaner to clean out any odities. I then reinstalled AHlll and guess what, exactly the same again - splash screen and then nothing.
I checked the task manager to see if there was any element of it running in background, but no sign. I then checked that other hi-resource programmes ran OK, Cubase 12, Photoshop, Lightroom & Bridge, all running at the same time with no issues.
I messaged Hitech yesterday via WhatsApp and I know he has read it, but no response so far. I think I will give it a week to see if there is any chnge and if not, then I guess I will have to call it a day. Its a shame, it's been fun.
