NAV 2009 causing DVD/CD problems

Hi,

 

Following my upgrade to NAV 2009 in May I was getting the blue screen of death every time I put a rewritable DVD or CD into my laptop. Last week I found this http://www.symantec.com/norton/support/kb/web_view.jsp?wv_type=public_web&docurl=20080929165146EN on these forums and followed the instructions.

 

Now instead of the BSOD I get a D drive inaccessible message when I try to use a rewritable DVD/CD. Any help would be much appreciated. Thanks.
