TimeTrex Time and Attendance

I received the following error when trying to upgrade from Standard edition 5.1.0 to Community edition 7.1.0:

There has been an error.
Error renaming C:/TimeTrex/postgresql/data to C:/TimeTrex/postgresql/data.old
The application will exit now.

Now when I try to open TimeTrex I am unable to do so. How can I fix this?

Thank you,
Jessie Hill

Try rebooting and attempting the upgrade again.

Also make sure you are logged in as an Administrator when you attempt the upgrade.
