After the upgrade, to P8, my virtual machines are not working anymore. After startup the message "One or more kernel components are for another version of Parallels Desktop" appears. The further the system provides the advise "To solve this problem, restart your mac and try again". Version info: Build 8.0.18101 (Revision 797180; Wed, 05 Sep 2012). Could someone please provide some advise? Regards, Bert
