Yesterday (Sunday) one of my Premieres was kind of wonky for several hours. I had one of those 'N33' errors and, while I WAS able to navigate everywhere I needed to go, it was as slow as molasses in January. I don't know what the heck was going on. I didn't have that problem with the other Premiere.
I was almost wondering if they were working on the update but, alas, I have the same version. The 'N33' error finally went away and operations were normal again.
