project 2010 standard visual report error with office 2003

Hopefully I am doing this right I have never posted a thread on a forum.
Just wondering if anyone can help me out.
I have Microsoft Project 2010 standard, office 2003 and Windows XP.
I have created a Gantt chart and when I try to do a baseline work report I get an error saying "An unknown error has occured. An error occured and the requested action could not be completed at this time."

Can you try to follow the below website to get some information about the "level of usage data" option:

Thanks for your reply it is really appreciated.
I followed the link and followed the creating a visual report step by step and changed the level of usage to every option and still got the error.
I have tried to create the baseline work report selecting excel only. When I click on Visio it gives me no options in the all tab. I have Visio 2007.
Not sure if any of this info helps.

Do you have resources assigned to the tasks and have you saved a baseline?

Can you run any of the visual reports in Excel. Do you have SP-2 applied to Project 2010? In order to use Visio - it must be the Professional version of Visio.
