pyUC P25 "not linked"

Scotty 2543G KD2LWH

Hey guys,
The first time I started pyUC and switched modes to P25 it worked, no issues. Everytime after, I try to switch modes and it says "not linked" when I hit P25 and goes back to DMR. Any ideas why? I didn't ever "link or unlink" anything. Thanks in advance.
