Pokemon Stadium 2 trouble...

??? Every time I try to load a save from Pokemon Stadium 2, I get the 'You've performed an illegal operation' sign. It doesn't do this with any other game, either... I have the latest version of PJ64, if that makes any difference... Help!

more problems

Oh yay, more problems. Now, every time I open up PJ64 (not a game, just the emulator in general) I get these two messages:

"Graphics Error
Direct3D failed to initialize your HAL device.
Make sure you have a properly configured 3D graphics card compatible with Direct3D 6.0."

"Error
The default or selected video plugin failed to initialize.
Most functions have been disabled.
Consult plugin documentation or start another plugin."

Any idea what this means? The game was working fine a few minutes ago.....

???

oh... you're right... but...

Oh yeah... I had the old one...

But I just got the new one, and it's doing the same thing to me! Is it just my computer that's messed up?

This is just not making sense... Say I open up PJ64 and a rom, blah, blah, blah, it plays well, then I close it. I go to play again later, and it doesn't work. I go back the next day and it DOES work! Is this normal??
