SQL History is blank

Navigate to %localappdata%\Red Gate\SQL Prompt 11\SqlHistoryIndex and rename the SQLHistory.db file to something like "SQLHistory_OLD".

Then re-open SSMS and a new SQLHistory.db file should be created in that folder.
 
If it still fails, please raise a support ticket with a copy of the SQL Prompt log files. To find the log files for the current session, open the SQL Prompt menu, click Help and then click Zip Log Files.
