kendall, if I remember correctly, you got a new computer with WinXP as the operating system. If so, click on Start/Run, then type in msconfig into the dialog box. Click on OK to run the system configuration utility. When it loads, click on the Startup tab. You'll see a list of programs which run at startup. If the Paltalk uninstall program is listed there, click on the checkbox at its left to clear the checkmark. Then click on Apply, give it a few seconds, then on OK. You'll get a message box that the computer must be restarted for the new configuration to take effect. Makes no difference which choice you take - the configuration will update the next time you restart the computer anyway.
If the Pal uninstall isn't listed there, then it's buried in some esoteric place in the registry.
