MS Office 2003 License Agreement keeps coming up

I bought an Office 2003 program from Ebay and have installed it on my Vista computer. Now, whenever I start up Word or Excel or Outlook then I get the License Agreement. How can I stop this thing? Please help

To resolve this behavior, follow these steps:

1. Log on to the computer by using a user account that has administrative credentials.
2. Start an Office program, such as Word. The End User License Agreement dialog box appears.
   Note For Windows Vista, click Start, click All Programs, click Microsoft Office, right-click an Office program, click Run as administrator, and then click Continue.
3. Click I Accept.
4. Exit the Office program that you just started.
5. Repeat step 2 to step 4 for the other Office programs that still prompt you with the EULA.
