I am running 2015 SP 2.0. Since on 2015 I have been getting a message most of the time when using "Copy with Mates." I see there are several issues with mates in general in 2015, but I have not seen anyone complain about this. I am not encouraged by that... Does anyone else get this message?:
And if so, is there a known solution? Sometimes I have been able to use copy with mates, but generally I get this message and cannot get it to work.
