Pervasive Database Pre-Load (Not Starting even though in Startup Menu)

SUGGESTED

We installed Estimating 13.1 two weeks ago and are now experiencing some problems with the Pervasive Database Pre-Load not starting up when the computer starts.  We have verified that the Pervasive Pre-Load is in the Start Menu and have done a reinstallation on one of the machines.  We usually discover the problem when the user goes in to open estimating and it will give a I\O error, we have tried stopping the Pervasive Pre-Load and re-starting it, but the machine will not allow this action as it says "it is already running".  Our temporary solution has been to reboot the computer and then immediately go in and Start the Pervasive Database Pre-Load.  If we do this then Estimating will work correctly.  Curious if others are having this problem and whether they have discovered a solution.  Additional information, we are experiencing this issue on 5-6 machines.  Thank you
