CRASH after closing session and opening another

After creating a new session from a template i created with several plugins in the master track and Virtual Instrument Kontakt 5.3, if i save and close the current session and try to open a recent project or create a new project from a template Cubase Crashes

This happens EVERY time…
My Cubase Installation was made from zero in a new iMac from version 8 to 8.03…
Please help me find out the reason of this problem

Thanks

Hi and welcome,

This is very often plug-in related.

Make sure, all of your plug-ins are up-to-date, please. If it’s still present, try to reduce the plug-ins in the template to find, which plug-in causes the error.
