If the HP drivers are much older than that, you may want to consider contacting them for an update.</P> <P>&nbsp;</P> <P>As for sending private messages - I see an option in Preferences (see top of this forum page when you are logged in) &gt; Preferences (tab) &gt; Private Messenger (tab) &gt; Turn on private messages.&nbsp; You may want to turn it on if it is not already.&nbsp; Then you can hover over my name/avatar and click on "Send message" - if it doesn't you may want to search the forums for the exact error message you receive.</P> <P>&nbsp;</P> <P>BTW are you, @Anonymous and @Anonymous the same person?&nbsp; It's not clear to me whether we're dealing with the same problem here or two unrelated issues, each of which deserves it's own thread.</P> <P>&nbsp;</P> <P>@Anonymous's crash seems to be related to a fix we've made in R2015.3 so upgrading to that should help, as <a href="https://forums.autodesk.com/t5/user/viewprofilepage/user-id/2003159">@andre.barth</a> said.</P> Mon, 24 Aug 2015 19:38:00 GMT hgohel 2015-08-24T19:38:00Z
