4.0.0 through 4.0.2 don't work

[EsEmDee]

Hello! New member here. I downloaded Dolphin, version 4.0.2, and tried a couple of games. The first one, Super Smash Bros. Brawl, didn't work, just gave me a black screna nd an error that told me Dolphin has encountered a problem ands needs to shut down. Same thing with the other game, New Super Mario Bros. Wii. At first I though it was just a problem with the games I'm testing, so I first posted something similar in the Brawl topic. But, I tried downloading some older Dolphin versions, and 3.5 seemed to run the 2 games just fine (Tho they ran slow, which is why I want to use the latest version), so I thought it would be better to post the problem here, rather than the Brawl topic. What could be causing the version of the emulator not to work? I'm running the 86x version on my Windows XP 32-bit machine. Thank you!
