Is there an anwswer in this link? All I find are problems related to Dell computers, which do not apply to my problem, or to contact tech support...

[Walter Roberson]

That link is all the publicly known information about the problem. If none of those solve the problem, then you will need to either contact technical support or do without.

In some cases you might need to regenerate prefdir
