DBACOCKPIT --> Error Message no. 1R360 & SQL Statement History is not being retained ...

when using TCODE "DBACOCKPIT" --> Performance --> History --> SQL Statement History, I am having two issues:

1) Error Message no. 1R360 -- When I try to view an single SQL Statement (screen: SQL Statement with no parameters), then select SSMS tool, I get this error ... Any ideas why my SSMS tool will not launch anymore? I've upgraded my desktop version of this tool, but not sure what/where to fix this issue.

2) SQL Statement History is not being retained -- I've reviewed the "DBACOCKPIT" --> Configuration --> Monitoring Environment --> Monitoring Configuration --> STMTHIST configurations (all correct) ... But it is only retaining a few hours of data -- any ideas?

THANKS FOR YOUR HELP!
