Heidi Module load error

[Whalco]

This is a new install of Freestyle on Windows 7 (HP Pavilion p6531). The program seems to work ok, but comes up with the error message on startup each time I use it. I have included a picture of the error box as an attachment (note: I enlarged the error box [in relation to the program] so that I could show the whole program  as a smaller image).

Please check your DirectX configuration, if you have DirectDraw Acceleration disabled.

Go to Start > Run > then type dxdiag in the open dialog box and click OK.

DirectX diagnostic Tool should open. 

Now click on Display tab and make sure that DirectDraw Acceleration is enabled.
