Exportation crash

There have been problems reported here with exporting on a recent update of Premiere.  First, always a good idea to tell us your system specs: OS version, Premiere version, amount of RAM, Hardware specs including graphics card when posting a question.   Do some searching here and you'll find similar posts and workarounds/solutions.  You may need to roll back the version of Premiere you're using or do an update or install the beta version.    I'm always very careful updating any software in the middle of a project and if things go south, ready to revert to the software version that was working.  Premiere makes it very easy to revert to an earlier version.  And generally a good idea NOT to enable automatic updates.  If you need any help with this, post back.    And it's really useful to monitor this forum on a regular basis so you're aware of problems that other people are experiencing.
