Sonar 64 on XP 64 - VST plugs vill not load - Sonar Hangs

Trying to load my projects, but Sonar will only load them if I have less than 5-6 VST plugins. The loading will take up to 2 minutes. If I load songs with more than 7-8 VST Plugins Sonar (501) will just hang and die.

Is there anybody out there with a 64 bits system that works witn VSt plugs and BitBridge?
