Smart cant execute queries

Hi all,
I am trying to run queries in SMART and it keeps failing. Anyone knows what could be the problem and most importantly how I can fix this?

This problem started after I updated my SMART software from 7.5.6 to SMART 7.5.9

I have attached a picture of my error log.

Try closing and then rerunning SMART and try the query again. That error shows that you can’t access your database, there might have been some previous error that crashed the connection.

Hi Jeff, I have tried that and still no win.
Can I delete and uninstall my SMART and re-install it? do you think it will work

yes that should work, try installing smart 7.5.9 from the download here: Download SMART 7
