Instructions on how to disable UAC on Vista
Click START and then select CONTROL PANEL.
Type UAC in the search bar at the top of the screen. You will see this task presented.

Select Turn User Account Control (UAC) on or off
Select CONTINUE on the next screen
Next you will be presented with the window shown below.

UNCHECK the check box where it says "Use User Account (UAC) to help protect your computer."
Click OK and then click Restart your computer.
Easy Pool will now allow you to delete one player at a time safely.
We do suggest you back up your data file after turning off UAC. The data file where all your players picks are stored is called ezpool2008.tdb
This is found in the Easy Pool 2008 Folder under Program Files in your directory tree. Just make a copy of ezpool2008.tdb and store it some where else on your computer.
