Little Rock Public Safety not working anymore.

[theshepherd3]

I had programmed in the Little Rock Public Safety trunking system (Arkansas State,Pulaski County) into my scanner and everything was working great until a couple of days ago. All of the other talk groups/trunk systems I have programmed are working. Any Ideas on what I may need to do to get this up and running again?
I have a Radio Shack Pro-107. And am using the ARC500 software.
