Error "Attempted to read or write..." DAOpenFile

   Hi!

Sometimes when I use DAOpenFile() function to open PDF files it raises an exception "Attempted to read or write protected memory. This is often an indication that other memory is corrupt. at QuickPDFDLL0715.dll.DelegateIISS.Invoke(Int32 P1, String P2, String P3) at QuickPDFDLL0715.dll.PDFLibrary.DAOpenFile(String inputFileName, String Password)..."

I'm sure that file in not locked by other applications. 
Did somebody experience such problems ?
