Which release of Platinum?
Is your Windows current with all maintenance?
BIOS, Firmware, & Drivers for audio interface and other system components all up to date?
Have you gone into the Windows Event Viewer to see if there are any recorded errors that correspond to the same times as your general errors?
Are you using any 32-bit plugins in a 64-bit environment?
Are there any steps that you can post back with, where it seems more likely to happen? Maybe some weird glitch is set up only when a particular set of things are done in a certain order, that kind of thing.
It would seem to me that since there are not a whole bunch of folks with this error posting a bunch of threads about it, that it is likely local to some configuration issue or possibly some plugin being a little flaky. That might mean it is solvable, once its source can be determined.
