Dell is responsible for configuring and distributing the graphics drivers of its laptops, but it looks Dell dropped the ball for your model. If you're not afraid to take a bit of a risk, you could try the Omega Drivers. Link I'm using the ATI Omega drivers for my Radeon 7500 Mobility and the game works.

In a recent game, I had the temporary prision planet UP issue occur. My empire recieved the prision, and according to the resolutions text, it was placed on my most productive planet for three years. The planet in question has text in the details screen stating that there is a prision which triples production, but the values for Social/Military haven't changed from before the UP meeting.
I just played a game on medium and developed a long-range colony ship just so I could grab the last three planets in a portion of the galaxy far away from everyone else. There's no problem with range as it is. Also, what makes you say eXploitation isn't in this game?
No, all class 0 planets are uninhabitable to all races. They're there to provide "terrain", but I think there's an event that can make some of them usable. Edit: beaten by Frogboy.
"Does that use a divx codec coz im not getting any video." Nope, it uses the Windows Media format. Make sure you have the latest driver for your graphics card, and are you using Windows Media Player 9 or 10? And yes, more videos, please.
