Experiencing too many problems with 2012 release. IE9 seems to have been crippled by it on all 3 machines I use plus various other minor but irritating issues that seem to already be documented here. This seems a particularly sloppy release, to be frank. Anyway, my question is how do I revert to NIS 2011 if I do not have the installation files? Are they available from Symantec? Thanks.
