Spark crashes all the time Logic 9.1.8, 10.8.5

[daritimm]

I have the latest 1.7.2 Beta and the Vintage Drum from the V3 collection and somehow it keeps crashing every now and then. Works fine for a week then has a couple of days it crashes when I open the plugin. Or when I playback it gives me a HUGE loud pitched screeching sound. When it does that nothing to do but restart the computer a couple of times and hope for the best. Few days later it works fine for a couple more days. Impossible to work with. Here's the beginning of the crash report. Have the full file available.
