1. No 
2. Probably no
If you really want to record at 48k don't use KPA's s/pdif out. The message and the related problems will probably vanish. Or simply change to 44.1k if you want to record digitally.
You can access 48kHz in the hidden Artists' menu, although it's not officially supported. I can't remember offhand what the combination of key presses is, but @skoczy or @DamianGreda probably know...
I use a Behringer SRC2496 between my KPA and Audio Interface. I record everything at 96k, and the Behringer allows me to set whatever sample rate I need. Works great. You can usually find them used on Ebay.

Is this It?
"It's in the artist menu which is a hidden menu. Go to the system page, hold rigs for 4 seconds, then go to page 5."
Found it in an old thread.
