Hi, I've created a vsto 3.0 outlook 2007 plugin with visual studio 2008 (so I guess that I dont need to make a com shim because of the new security system). The assembly is signed and it gets installed and loaded. It works well for a few days but, suddenly, stops loading and I get this exception on the event viewer thrown by VSTOR3.0:
VSTOR3.0
Exception: Customization could not be loaded because the application domain could not be created.

I can get the plugin loaded only by uninstalling the plugin, vsto 3.0 sp1, vsto 3.0, rebooting the machine and then reinstall all of them! I cant do this always!!
I really dont know what to do, maybe I have some domain policy groups problem?? Or I must create a Com Shim?? I guess that the last one wasnt needed with the new vsto!!! Please someone help me :(
