Acid Pro 8 upgrade freezes at certain plug-ins (both 64 and 32 bit versions). NOT always the same ones. Acid Pro 7 (from Sony) works fine as does all my other audio software. Magix wants me to move my plug-in folders, however, I am NOT moving them and causing potential problems for my other software to accommodate an obvious problem with Acid 8. I don't think it is ready for prime time. What a disappointment. Sony Acid 7 is working far better. I waited 10 years for this??????
