Error 70 (Permission Denied) ModNIFastRead

This has only started happening. I have been using PDFCreator 0-8-0 without problem for some time.

Full message is Modul: ModNIFastRead

Procedure:ReadToString

Line 50050

 

This is different to the other message in this forum in that it happens in a different module.

I've reinstalled PDFCreator to no effect. What is the likely problem?

Cheers
