Absolutely!!! the same issue. I am using the IMACPro with Nuendo 8.2.1. Exporting mixes gives me intermittent -38 error with the UAD-2 QUAD Satellite module in which plugins are disabled. The only short term fix I have found is exporting the mix in “real time”. I am in contact with UAD about this issue. They directed me to the this posting in the forum today.
