Hi Warren,
I haven't tried reinstalling yet - I don't usually default to that. :) So with this Media Encoder, I guess it is used for more than I've been using it for which has always been just while rendering. What do folks typically use the encoder for?
I haven't tried opening files in encoder because frankly, I didn't know its use really.
Also for all - It's not an specific file and seems very random. One file may work once, then not again or one that didn't import the first time may do so on a second try.
Thanks,
Eric
