Amplitube 2 crashes Sonar 3PE?

I have run into a little trouble with Amplitube2 in Sonar. Every time I add it to an FX bin, Sonar crashes somethin' fierce... I have been able to work around the problem slightly by adding the dxi to a bus instead, and sending whatever guitar track through there. But it still crashes upon loading certain presets.

Just wondered if anyone had a similar problem, and wanted to share some possible solutions?

muchos gracias,

Pc specs, os, soundcard, buffer settings, driver mode. Please list all these if you would like some feeback

Dell Dimension 8200, P4 2.39 GHz, 768MB Ram; XP Home; EMU 0404 w/ latest drivers; Sonar 3 PE in Asio mode-- 50 second latency buffer, i/o buffer size 64 kb... what else... uh... oh yeah, recorded file bit depth at 24 & 44.1.

Thanks Cj,

Unfortunately I tried that and Amplitube still crashes Sonar... Aaargh!!
