I had changed no settings, everything was as it should be, and during a mix session i wanted to put the softube Drawmer S73 plugin on the track. No troubles i thought, have used it plenty of times. It proceeded to crash S1 4.6 pro. AAHH! So after i loaded the program up again i tried to remove the S73 plug. Wouldn't remove it, and it shut the program again. Now i have a few softube plugs across a few tracks, including the excellent amp room, and the plugin still works as it should, but won't load the GUI, and if you try to open or remove the plugin, it crashes again. Happens in S1 5 as well. Only softube plugins. No others. I have also un-installed them and re-installed them. Any one have any insight into this? I have sent a few emails now to softube support, but still waiting for a response. Each and all of my plugins are fully up to date, as with S1 4 and 5. Windows 10, ryzen 7, 32gb ram, all current and up to date and working as it should.
