So, apparently Waves rolled out an update for all my Waves plugins that I was not aware of. Once I applied that, the problem went away!
However, now every time I open a project I get a warning about Breverb not being recognized and asking me to choose one of two different installs, neither of which makes any difference. I reinstalled it and it still gives me the warning. Once I click through the warning, Breverb works but, I'll have to see if I can get that figured out
Also, I had to get a new computer so, this is a new install of Cakewalk. It just dawned on me that, because I no longer have my old install of Sonar Platinum on this computer, I no longer have access to all the stuff that came with it. Is there any way to get my old Sonar Platinum back??
