I've tried the idea of pulling out the power and batteries but that didn't make any difference.
After alot of analyzing it seems that I can curve the ball left or right BUT It's absolutely IMPOSSIBLE to make a straight shot, not even nearly straight, it's absolutely impossible and I know that I certainly made straight shots before, also if I'd like a curve shot it's highly erratic now compared to how it used to be. Something must have happened, I just don't undetstand WHAT. I haven't dropped the wii or crashed the wiimote into something etc, I haven't done anything, just turned out like this all of a sudden. I'm thinking about whatever it can be an system update that made this behavior but I guess others would have the same problem then.
Any other ideas? anyone? I'm out of ideas!
