Guitar Rig 5 Pro stopped working, cutting in and out. It was causing my DAW playback to sputter. It was installed in 2012 and worked well. I thought uninstalling and re-installing would fix it. I hit the download button but was prompted to install Native Access. And, naturally, an error message popped up say it was an invalid app. I'm not really a computer wizz, so suggestions would be appreciated with that in mind. I'm just at the beginning of a project and need a solution. I don't know if I can buy Guitar Rig 7 and get the upgrade price. Any help help appreciated. 👍️
