I can't get any realtracks to work at all. They were fine when I first installed 2010 on my AMD64 X2 +4200 dual core Windows XP Pro 32bit machine. Then after a couple days of use, one of the songs I wrote wouldn't load with a violation access error and now I can't load and play any style that has RealTracks and/or RealDrums in them. The build I have is 292 and yes, I have defragged and optimize and restored to factory settings until I'm blue in the face. As far as I can tell, I have not access to any of BiaB that uses RealTracks or RealDrums.
I'm happy to say the old midi styles are functioning perfectly.
