Weird IK Multimedia Problem

Since end of last year, I've purchased TRacksCS, Amplitube3 and SampleTank3. They all work normally except for one thing: if I load any of them, load a module inside them, unload the module (or leave it there) and try to de-instantiate the plugin, the PT11 along with the entire computer crashes. HARD! I have to force the computer off and restart it to regain control. If I DON'T load a module, just load the plugin and leave it empty, the problem does not occur. Also, I can load all the modules in TRacksCS as separate plugins with no problem. I've sent crash logs to both IKMultimedia and Avid. Both say the logs show there's a permissions violation. IKMultimedia gave me a list of all the files that they think could be causing it and I verified each permission in each file many times. No help.



Anybody else seeing this? Anybody got any ideas what might be causing it?

Thanks in advance!
