Bugged Menu?

Hello, and thanks for taking the time to read. I hope someone out there can help me, because I am at my wits end ~:confused:

When I start up RTW, the menu is, well, bugged. When I move the cursor, it leaves a trail, and when I click on an option, it merely superimposes it over the menu so that I can barely read it.

Also, when I do manage to get in the game, clicking on the Senate tab crashes me to desktop. I installed the Windows Media stuff that came with the game, but not the Direct X because I already have version c.

Any help would be appreciated!
