Xmage doesn't run, black/ugly screen (d3d problem)

I have been playing xmage for a long time in my pc (Windows 7). Recently it doesn't launch anymore. Whenever I try to launch, the physical memory starts to rise and xmage never launches. I've already tried uninstalling java and xmage, and then reinstalling both; also tried download the zip file and launch it directly from the executable (without the launcher). Sometimes it launches a few times before it stops launching and never launching again. Someone having #a similar problem?
