Hello Brian,
You may need to reinstall Quik Link, in case the Excel Upgrade overwrote or removed necessary files. Those error messages are being returned from Excel.
In Office 2000, you can set different levels of security for macros. If you have the Macro level security set to Medium, then every time you use Quik Link, you will be prompted whether to Enable macros or not. If the security is High, then you will be unable to run Quik Link at all. Perhaps (temporarily) set the security level to Low and give it a try.
